Sets for cutting and expanding brake pipes. How to flare the brake pipe with your own hands? Step by step description of the process

if you have own car, then you simply have to study its design and mechanisms from time to time, so that in the future, in the event of a breakdown, you can repair it yourself. And in general, every motorist should understand cars, at least within the limits of his car, and in case of the slightest deviation from his normal operation, he was able to prevent the failure of any part or the whole mechanism in time. For those who are just learning to understand a car, I will talk about what flaring of brake pipes is. Also, everyone will be able to find out what a brake pipe is and how it is used for a car.

In order to have a clear picture of what the brake pipes are for and what role they play, you do not need to consider them as a separate element, you need to familiarize yourself with the entire brake system of the car. Thus, having understood the operation of the system as a whole, the task of the tubes will be clear. The braking system, superficially, works in this way: if it is necessary to slow down or brake hard, the driver depresses the corresponding pedal, and the piston located in the main cylinder, under high pressure, begins to drive the liquid along special paths.

The very same braking or a complete stop of the car occurs at the moment, at the moment of converting the forces of fluid pressure on the wheel cylinders into the resistance of the brake pads. So, the paths along which the piston drives fluid to the wheels consist of brake pipes and hoses. The failure of any part of the system leads to the breakdown of the entire braking system, and therefore, your car becomes unusable.

When is flaring required?

With poor transmission of fluid through the tubes, the car brakes with a delay, and the braking distance is almost doubled. Also, in the operation of the system, it is especially noticeable when the brake pedal is pressed, extraneous sounds appear, as well as some pulsating movements. The movement of the pedal, while pressing it, will seem a little free to you, this is very typical when there is a malfunction brake system, namely brake pipes and hoses. Also, one of the reasons for the malfunction of the tubes is the visible leakage of fluid and the brake system. This leak will cause the brake drums to overheat and wear the brake pads unevenly. Another sign may not be the usual behavior of the car while pressing the pedal, namely, the car moves a little to the side. Of course, this is an indirect reason, but, according to experts, it may indicate a malfunction of the tubes.

The most obvious symptom that the tubes are starting or have already worn out and it's time to deal with flaring is an increase in braking distance.

It is important to know that the main problems due to which tubes break quite often are:

• destruction of the structure of the hexagonal head;
• litter and dirt getting into places threaded connections or the ingress and coking of liquid in these places.

The above troubles cause very great harm not only to the elements, but to the entire system. If the owner wants to protect the car from this kind of trouble, he should remember that it is necessary to test the car's brake system at least once a year. If we equate the elements and the system itself to mileage, then diagnostics must be carried out every 50,000 kilometers, and parts, in particular rubber tubes, change after 125 thousand kilometers, no matter what technical condition they are.

Flare instructions

Not every driver has a pleasant feeling about car repair. Many do not want to crawl under the hood and repair the breakdown, to say nothing about the repair of parts, for the repair of which it is necessary to climb under the car. Yes, pipe flaring is not one of the most pleasant jobs, but it is not very difficult either. The most important thing is that you can flare yourself, and at the same time do not pay some "specialists" at the service station. For the qualitative performance of this work, you need to purchase a special device, the so-called "flaring tool". Such a set for expanding brake pipes, in which you can see a pipe cutter, fitting, pliers, can be purchased at any automotive store, besides, its price is a penny compared to the price of work at a service station. You also need to prepare some gasoline in a bottle for further lubrication of the pipe and a drill for chamfering.

So let's take a look detailed instructions how to flare a brake pipe.

The tube is unscrewed by hand from the cylinder or caliper. The damaged area is determined on it, and if possible, we repair it, otherwise the tube is not suitable. So, with the help of a pipe cutter on the damaged area on the tube. After that, you need to process the serviceable cut edge of the tube with gasoline. Using pliers, we clamp the tube to create a connector for the fitting. We take a drill and a drill of the required diameter and remove a little edge inside, make a chamfer. After that, you need to clean the seat from chips and insert a fitting into the tube. Now the most important thing - flaring. The flaring tool is used as follows.

The edge of the tube is inserted into the special holes of the machine in such a way that a segment of about five millimeters remains over the grip and is clamped. The mechanism processes the desired part of the tube. In the case when it is necessary to flare both edges of the pipe, then the second one is performed exactly according to the same scenario as the first edge. After completing all the above steps, you should have a neat extension. The size of the extension can be varied on the machine, and it depends on the specification of the car and this is provided in the kit (you can see a special pattern in the kit).

So, summing up, we can say that the work of expanding the brake tubes is not very laborious and complicated. It is important to understand that most repairs regarding an iron friend can be easily done on your own. And this is very important, because by fixing the breakdown personally, you can not only save money, but most importantly, it is possible to do the job better than any car mechanic. The main thing is to follow the instructions and remember that this is done exclusively for yourself.

Video “Replacing brake pipes on a car”

The recording shows how you can replace the brake pipes on a VAZ car.

Trouble-free operation of the brakes is perhaps the most important factor that affects the degree of safety. traffic and car use. The basis for the immediate repair and replacement of brake pipes is the slightest suspicion of a violation of the operation of these simple but important parts of the braking system.

Failure of the supply pipelines leads to the failure of the entire braking device, and can lead to the most unfortunate consequences. Strict supervision of the tightness of the brake pipes and the places of their connection with the actuators is the basis for safe operation vehicles.

The company ″Tehkom″ manufactures brake pipes in Moscow and the Moscow region. Own products of the company ″Tehkom″, which it produces for braking systems of various vehicles, according to technical specifications in no way inferior to products of well-known brands.

The manufacture of brake pipes for foreign and domestic cars, in the company's workshops equipped with modern technology, takes just a few minutes, while the cost of manufacturing is much lower in price compared to standard factory-made products.

The company ″Tehkom″ uses only proven steel and copper pipe parts. It is possible to equip with any kind of tips and flare tubes for connecting elements of brake systems with hydraulic, pneumatic or mixed drive, for almost all car brands.

The service for the manufacture of brake pipes includes:

1. Recommendations of specialists on the choice of material depending on the type of car and its operating conditions.
2. Cutting pipe sections to the desired length. The size is determined by the catalog or by the sample of the product that is out of order.
3. Selection of the appropriate type of threaded tip or other type of fitting.
4. Rolling of tube ends for the most common types of connections used by both European and Asian vehicle manufacturers. These are, respectively, the ″fungus″ and ″inner cone″ types.
5. Bending tubes according to a template or sample.

The price of products to a rather small extent depends on the number of operations performed, since they are all produced on modern semi-automatic equipment and the complexity of the process is relatively low. The main influence on the cost is exerted by the material and dimensions of the products. Steel parts are cheaper, but rust rather quickly, especially in winter, when roads are sprinkled with various chemicals.

In addition, rigid steel brake lines are quite difficult to fit on site. Despite the higher cost, preference should be given to the manufacture of copper brake pipes, which are practically not subject to corrosion, are durable and, thanks to the plasticity of the material, are easy to install even in the most inaccessible places.

The lion's share of accidents on the roads is due to the failure of car brakes. A common cause of such failures is damage to the brake pipes. Be vigilant and even with the most insignificant, at first glance, their malfunction, contact the Tekhkom service centers in Moscow. The company will provide fast and high-quality production of tubes for brake systems of any car. Do not endanger your life and the lives of others.

Flaring the brake pipes is a procedure that may be required at any time by someone who owns a car. Of course, the implementation of this and any other operation related to the maintenance and repair of cars vehicle, you can always trust qualified service station specialists, but many motorists go the other way and try to do everything with their own hands. Each car owner has the right to decide for himself who to trust the maintenance of his vehicle, but many of these issues can be resolved on their own.

Functions of brake pipes

Brake pipes are an integral part of the braking system of any car, which is responsible for stopping it at the right time. To understand the importance of such tubes for the operation of the brake system as a whole, one should at least superficially become familiar with the principle of its operation.

So, the process of stopping the car, for which the braking system is activated, consists of the following steps.

• If necessary, reduce the speed of the car or stop it completely, the driver presses the brake pedal.
• The master cylinder piston connected to the pedal is actuated and begins to act on the brake fluid.
• Under the high pressure communicated by the piston of the main cylinder, the liquid begins to flow through the tubes and hoses into the cylinders of each wheel, already acting on their pistons.
• Under fluid pressure, the pistons act on the brake pads, which are pressed against the brake discs, stopping the rotation of the wheels.

Obviously, brake pipes play a crucial role in the operation of the entire brake system, and if they break, it completely fails. That is why the repair of these elements, to which and applies, should be approached with all responsibility.

When is it necessary to flare brake pipes?

Through the brake pipes, as mentioned above, high-pressure brake fluid is supplied to all elements of the system. When the capacity of such tubes deteriorates, the whole system begins to work inefficiently, which leads, in particular, to a significant increase in the braking distance. The following characteristic signs may indicate that the elements of the brake system, including tubes, require diagnostics (and, possibly, repair):

• the appearance of extraneous sounds and pulsating movements when you press the brake pedal;
• free movement of the brake pedal when pressed;
• leakage of brake fluid, which leads to a decrease in pressure and, accordingly, to inefficient braking and intensive wear of the brake pads;
• driving the car to the side when braking (this situation, although an indirect sign, can also indicate that the brake pipes need to be repaired).

However, the main sign that the brake pipes do not fully perform their functions and require flaring is an increase in the braking distance. The most common causes of deterioration in the performance of brake pipes are:

• violations in the design of the hexagonal heads with which such tubes are equipped;
• deterioration in the quality and reliability of threaded connections, ingress of litter or coked liquid into them.

Such malfunctions, negatively affecting the technical condition of individual elements of the brake system, significantly reduce the efficiency of its operation. That is why experts and automakers recommend diagnosing it every six months. If you are tied to mileage, then such a procedure must be performed every 50,000 kilometers, and rubber tubes, regardless of their technical condition, must be replaced every 125 thousand kilometers of the vehicle.

Technology features

Car repair, no matter what it is connected with, rarely causes pleasant emotions in a car enthusiast. This is also explained by the fact that such an event, as a rule, involves certain financial costs. Meanwhile, if we talk about a situation in which it is necessary to expand the brake pipes, the cost of such a procedure can be minimized if you do it yourself.

So, in order to flare the brake pipes with your own hands, you need not only to study in detail the theoretical information on this issue and watch the corresponding video, but also to purchase a special device. In, which can be purchased quite inexpensively at many automotive stores, includes the following tools and accessories:

• pipe cutter;
• fitting used as a connector;
• ticks.

Using such a simple set, to which you need to add a drill (to chamfer the ends of the pipes), as well as gasoline, which is needed as a lubricant, you can not only do your own flaring with high quality, but also save a decent amount of money that would have to be paid to specialists service stations.

Immediately before the flaring procedure with the brake tube, the following steps must be performed.

1. The tube is unscrewed from the brake cylinder or caliper with a tool or manually.
2. By visual inspection, the presence of damage on the surface of the tube is determined. If they are close to its edge, then the tube can be restored, if not, then it must be replaced with a new one.
3. Using a tool such as a pipe cutter, a damaged area is cut off from the edge of the tube and the cut edge is treated with gasoline.
4. The cut end of the tube is clamped with tongs and a chamfer is removed in its inner part using a drill with a drill of the appropriate diameter.
5. The section of the inner surface of the tube, where the chamfer was removed, is cleaned of chips. After that, the end of the tube is inserted into the fitting, which acts as a connector.

After all the above steps have been completed, the tube must be expanded, for which it is best to use a special machine. Flaring performed using such a machine is carried out according to the following algorithm.

1. The end of the tube to be flared is inserted into the clamping hole of the machine. In this case, the part of the tube protruding from the clamping mechanism of the machine should be approximately 5 mm.
2. With the help of a special punch, which is equipped with such a machine, the end of the tube is flared.
3. If it is necessary to flare the second end of the tube, the entire procedure described above is performed in the same sequence.

As a result of flaring using such a device, with the rules and intricacies of which it is best to familiarize yourself with the video, the end of the brake tube becomes neatly expanded. The use of a special machine allows you to adjust the parameters of such an expansion, because for the brake systems used on cars of different brands, they can vary greatly. As a rule, in special kits, with the help of which you can flare the brake pipes with your own hands, there is also a pattern that allows you to control the result of the technological operation.

The connection of fragments and parts of copper pipelines requires knowledge of certain nuances of the technology, which relate to both the soldering itself or threaded fastening with fittings, and preparatory work. One of the most difficult and responsible actions is the expansion of copper tubes. The essence of the process is that the inner diameter of one of the contact tubes must be increased, "adjusted" to the outer diameter of the other.

When fastening with threaded fittings, an increased clamping area is created and the conical chamfer fits tightly on the end of the adjacent section of the pipeline and the connection is sealed due to mechanical compression. In the case of soldering, the space between the conical outer part of the contact and the inner cylindrical part is filled with solder.

How a copper pipe is soldered using standard fittings is shown in the video, with a flared pipe the technology is the same and the connection is no less strong and tight. When properly flared, the end of the tube should look something like this:

To prepare the pipe for soldering or threading, a special tool for expanding copper pipes is needed. It is called differently - roller, flaring, rolling. But the essence of this does not change - subjected to mechanical stress, the tube is deformed according to the pattern and, retaining the wall thickness and circular cross section, forms a cone. The slope of the inner walls of the cone is up to 74 0 . For connections using a union nut, pipe processing must be carried out in accordance with GOST 13954-74 or as close as possible to its requirements. If you use commercially manufactured rolling tools and adhere to all the requirements of the technology, you should get a result corresponding to the scheme:

The ratio of the diameters of the pipe body and the maximum allowable outer diameter of the cone D and D are given in the table (for standard sizes copper pipe).

The flare for copper pipes is produced with nozzles of various sizes, which meet the requirements of standards for both soldering and union nuts. When buying imported instruments, especially those of Asian origin, it is imperative to check the conformity of matrices and cones so that their sizes do not deviate from those accepted by us.

Types of expanders

A cone expander is a pipe expander that acts by direct pressure of the cone bushing on the pipe. It is very easy to use and quite convenient to use directly on the site. It won't take up much space in a fitter's or plumber's suitcase. Tool weight no more than 0.5-0.6 kg. The figure shows a schematic diagram of a flaring machine, from which you can understand how to deform a small diameter copper tube in the right direction.

Diagram of a standard tool for .

1 - block for clamping the pipe;

2 - bracket with guide;

3 - screw clamp;

4 - conical punch (replaceable).

Such a flare tool for standard copper water pipes can work with diameters up to 10 mm. The tool is used in the assembly of air conditioning, heating, condensate drainage and water supply systems.

For large diameters, a certain force will be required, increasing almost exponentially, which can lead to damage to the tube wall, especially if it is of uneven thickness. A feature of the copper water pipe is some inaccuracies in the diameter and wall thickness along the contour.

With strong pressure, unforeseen difficulties may arise in the form of cracks, burrs and bumps on the rolled surface, which is an obvious marriage and such pipes cannot be used - sealing may be lost immediately after the fluid is put into the system or some time after the start of operation. The requirements for the state of the flared surface are regulated by GOST 28941.12-91 or specifications created on its basis.

• A - chips;
• B - cracks;
• B - uneven edges.

Eccentric flare

The flaring of standard copper tubes is of better quality and is characterized by the absence of defects if an eccentric flaring tool is used, the center of the cone of which is somewhat offset relative to the longitudinal axis of the pipe. It seems to roll on the wall of the tube, gradually shifting down and pressing it against the wall of the template, which is included in the tool kit and simultaneously performs the role of both a calibrator and a pipe clamp.

How a factory-made cone flare works is demonstrated by a roller. The diagram of the eccentric tool is shown below:

How to choose a flaring tool

When buying a flaring tool, there are a number of factors that must be taken into account that may affect the result of the work and the possibility of using the tool in specific circumstances. The main parameters are:

• pipe material;
• die hole diameter;
• the height of the pipe protrusion above the clamp cut;
• the distance between the centers of adjacent holes in the base;
• the outer diameter of the pipes with which you will have to work;
• tube wall thickness;
• flaring depth;
• type of pipe (welded, seamless, etc.)

For professional use, it is best to buy a professional tool.
It is, as a rule, manufactured according to a certain standard and meets all the requirements of GOST. The set certainly has a die with holes of the most popular sizes, the cone is perfectly adjusted and made of the best grades of steel.

For domestic use, the choice of a tool must also be approached with all seriousness - it is almost impossible to make a high-quality preparation of a pipe for a connection with a cheap tool. But there are no such high requirements as for a professional tool. Enough dies for 2-3 diameters and a cone made of simple polished steel. It costs much less and is quite suitable for periodic use.

How does the flaring of copper tubes with their own hands dismantles the video. Of the additional tools you will need a pipe cutter and an edge aligner (reamer). It is necessary to align the pipe in diameter in order to achieve a perfect circle contour - when cutting a copper pipe, due to its softness and plasticity, it is often deformed and this negatively affects the quality of rolling.

It is necessary to install the tube in the clamp in such a way that the upper edge protrudes 2–4 mm above the cut of the template. Only with such an installation can the maximum quality of the inner surface of the cone be achieved.

Flaring of brake pipes

The brake system of a car is the backbone of safety and needs professional maintenance. After all, driving safety depends on it. Today we will tell you about the most terrible breakdowns of the brake system, we will describe in detail what flaring of brake pipes is, why it is needed and with what tools it is produced.

Brake system malfunctions

Almost all drivers know that the brake system of a car consists of a control drive, distribution systems and executive (working bodies). All parts of the brake system are connected by brake pipes (pipes). These tubes carry pressurized brake fluid. In the process of pressing the brake pedal, the pressure on the TJ increases and it acts on the working body of the system, which locks the wheel and stops the vehicle completely.

During the operation of the brake system, the following malfunctions may occur:

• Violation of the tightness of the brake pipes and pistons, in which the fluid is under pressure.
• Mechanical failure of working bodies. This includes all kinds of jamming of brake cylinders, etc.
• Violation of the free play of the pedal. Such a malfunction makes the driver uncomfortable when operating the car.

In this article, we will focus on the first malfunction - a violation of the tightness of the connection of brake pipes with working mechanisms.

The brake fluid of a car contains an acid in its composition, which adversely affects thin-sheet metal products. In addition, constant exposure environment may cause corrosion on metal parts. In this regard, the junctions of the brake pipes with the working parts of the system may corrode and begin to release a special fluid from the braking system. The other side of the problem is the appearance of air in the system. This phenomenon reduces the pressure inside the brakes and contributes to the deterioration of the braking properties of the car.

To save money on buying new brake pipes, drivers go to remanufacturing the old pipe, which is very successful. This process is called flaring.

Flaring brake pipes with kit and tool

Flaring is any deformation or change in the shape of the tube, which is subsequently attached to a special product that connects the tube to the working body of the system.

This concept also applies to the braking system of the car. To make flaring, you need to have a special flaring kit. It includes a set of tools such as a cutting device, a deforming device and a set of tools for cutting threads on the brake pipe.

To carry out flaring, it is necessary to install the car on a viewing hole or overpass and immobilize. Brake fluid is drained from the reservoir and master cylinder. After carrying out all the activities, it is recommended to replace it with a new one so that in the future it does not climb again under the car. Unscrew the fitting of the damaged brake tube from its seat, and then remove it from the tube itself.

Cut off the damaged section of the line, about 5 centimeters. To cut the pipe, you need to install it in a special fixture and walk the blade around the entire circumference. After that, the cut end of the pipe is processed to get rid of irregularities that can disrupt the shape of the pipe, and hence its tightness of the connection.

After that, fix the end of the pipe in a special device and insert a rolling fungus into it. A threaded shaft is placed on top of the fungus, which is mounted on another fixing device. Turning the lever changes the shape of the cut part of the pipe. Then, depending on the presence or absence of a thread, it is cut on the pipe. In most cases, all brake lines are made without it.

Install the new end of the tube into the fixture and tighten the fixture nut. Before installing a new tube, it is necessary to clean the sealed part from grease. To do this, it is enough to treat it with acetone or gasoline. After all these measures, the fitting is installed in its place, brake fluid is poured into the system, it is pumped and after that the car can be operated again.

This completes the flaring of the brake pipes. As you can see, this is not a complicated procedure and almost any motorist who will have a flaring kit and other garage equipment on hand will be able to handle it.

In what cases is it possible to flare brake pipes with your own hands, and is it possible to do such things at all?

We answer immediately: such amateur performance is undesirable.

It is temporarily permissible only in emergency, force majeure cases, subject to a number of rules.

1. The car owner must thoroughly mentally imagine how the brake system works on his car.
2. He must have experience of such flaring, and not be taken for it for the first time.
3. A special factory-made tool must be available; it is not recommended to use various kinds of homemade products.

There are two options for flaring brake pipes:

• flaring in the form of a cone;
• in the form of a fungus.

The usual material for making tubes is copper, less often steel. What are the reasons for their damage?

1. Careless driving. Sometimes the owner of the car himself simply tears them up on obstacles.
2. Improper operation (bends, kinks, incorrect fixation, constriction, etc.).
3. Various kinds of chemicals and salt and other reagents with which our services generously sprinkle the roadbed in winter. Corrosion over time is guaranteed.

• With sudden braking, the foot on the brake pedal clearly captures the characteristic pulsations, a creak is heard.
• The braking distance lengthens for no reason.
• When braking, the car "leads" in one direction.
• The pedal travel becomes unusual (sometimes freer).
• Drums get hot or pads wear unevenly.
• Fluid leakage is visually visible.

In all these cases, you need to drive the car into a pit and carefully check the brake system. Perhaps there is a need for an emergency operation to resuscitate the system. What do we understand by flaring? The process of deforming the material of the end of a tube into a desired configuration. How to do it in real life?

Practical flaring of brake pipes with your own hands

First of all, you need a special flaring machine. Preferably factory made. Its kit includes:

• the machine itself;
• pipe cutter;
• interchangeable stamps:
• special bracket.

The algorithm for expanding the brake tube is as follows

1. The node is dismantled.
2. The cutter removes the defective area.
3. The working area is degreased (you can use gasoline).
4. The tube itself is fixed with pliers so that its length of about 50 mm is free.
5. A small chamfer is removed from the inside.
6. The fitting is put on.
7. The cut tube is inserted into the machine and flaring is carried out.

You can watch the whole process in this video:

Next, you should assemble the entire system, fill in the brake fluid, pump it, test it. Pay special attention to leaks. In conclusion, it is worth adding: if it is possible to entrust this operation to specialists, it is better to stop at this option. With your own hands, it is necessary to start expanding the brake pipes only as a last resort.

Do-it-yourself flaring of the brake pipe

When performing work on tuning the brake system, it simply cannot be done with just replacing the brake drum discs. Carry out a complete upgrade automotive system braking can only be started by replacing the pipeline on the hydraulic brake drive and completing the process with the installation of disk mechanisms. Before you start such work as do-it-yourself flaring of a brake pipe, you need to prepare the appropriate tool. Let's deal with the situation.

At the moment, in order to increase the economic effect and reduce the cost of a car, manufacturers of motor vehicles are currently installing steel brake pipes. Although more recently, the equipment of the hydraulic drive of the brake system was carried out using copper tubes, which have the properties of increased corrosion resistance, in contrast to analogues made of iron, and due to this, prolonging the overhaul run of the machine. When tuning an automotive braking system, larger copper tubes are usually installed in the hydraulic actuator, which automatically requires the replacement of all existing connecting nodes in the pipeline.

The most painstaking moment in the modernization process is the cutting of blanks, as well as the expansion of tubes. In the latter procedure, it is necessary to use a special tool to greatly facilitate the operation of tuning the brakes. Such a device has a pipe cutter, with the help of which they cut off the tube installed in the hydraulic drive. It is absolutely not difficult to work with the device and most car owners can handle it. The whole process consists in degreasing the surface of the tube with acetone, after which the workpiece is securely clamped in the device with a small segment of 5 millimeters remaining on top of the grip. Next, the end of the tube must be processed using a flaring mechanism. After that, the copper tube with a successfully flared end is released from the grip and two metal fittings are put on it. The next step will be a similar flaring in the device of the second end of the newly clamped tube. After completing all of the above, the copper tube can be installed in the required place for the hydraulic drive of the automotive braking system. We hope that self-flaring of the brake pipe will not cause you any difficulties.
