Where to unrest the brake tube. How to unraut the brake tube with your own hands? Step-by-step process inventory. Practical collapse of brake pipes with their own hands

Repair of the brake system often not only comes down to replace brake shoes or replace the brake fluid replacement in both circuits. More complex requiring accuracy and defined qualifications when installing is the repair brake pipes. Often it happens when through corrosion Or the destruction of the pipe due to an accident or repair of the brake caliper.

Repair of brake pipes with your own hands and successful connection of the brake pipeline to the distribution unit, tees, the main brake cylinder and brake caliper, requires high-quality processing of the end of the tube and the formation of flange cuticle, or the so-called "funnel". Get it using the brake tubing flavoring procedure.

There are several basic funnel options.

1. Eurostandard fungus (centered). The form resembles the tire of the wheel, is widely used in most cars manufactured at the Eurasian continent plants. It turns out the most durable version of the connection from the above, but is considered to be disposable. With a skillful formulation, you can use up to three times.
2. The usual simple funnel, obtained by the bend of the walls of the facet of the tube with a special tool for brake tubing rolling.
3. Funnel, obtained by double folding tube or simple funnels. It is considered standard in American cars. Get such a type of mushroom braking tube rolling tube, cauting its upper part with a conical mandrel.

The time of using a simple funnel has long passed, first of all, the metal has changed from which the pipes on old cars have been manufactured. Instead of soft and plastic rolled copper, a durable and solid steel pipe is more often used. If earlier the driver could unwind the end with the help of pliers, turning and a pair of blows with a hammer, then now it is impossible to perform the fading of steel brake tubes without fixture.

For your information! High Quality Connection Splitted copper tube In a simple funnel, it was provided only due to the plasticity of the metal and low pressure hydraulic fluid in contour. Do not attempt to connect the steel pipe with a simple funnel. Even if you wrap the fitting with great strength, the connection will not hold all-perky brake fluid.

How to perform the roller brake pipes with your own hands

The main condition for the successful turnover of the end of the pipe has always been the use of high-quality, and better professional, tool. For our cars, Europe-Asia, buy sets for rolling in metric design. Americans look more than worthy, glitter with chrome coating, but they can slip the inch system. The old Soviet standard for a copper brake pipe - 8 mm, more recent Soviet and Russian options used steel 6 mm.

In terms of choosing the most accessible, you can call the force 656b, 906t2 brake tubes, you can use more elegant jonnesway sets, or common Biltema or Licota.

The set of tools for the collapse includes:

• screw rolling press and clamp, with the help of which the screed of spikes and deformation of the brake tube metal is performed;
• two detachable plank-vise, having six - seven holes with cones, in which the tubes for the roller be pushed;
• cutting device allowing to cut off the end in a strictly perpendicular direction;
• a set of mandrels and cones of various diameters for forming fungi.

When choosing a breakdown kit, pay attention to the following points. The first, screw pairs of the screw-nut press and clamps should be black matte. This speaks about heat treatment and hardening the screw surface. In a cheaper option, a chromium coating is used.

Second, accuracy of the execution of calibrated holes in the straps of vice. Typically, the inner surface of the cones is covered with a protective oxide film based on phosphates. Such a coating facilitates the gliding of the deformable metal along the inner surface of the matrix.

Third, all calibrated holes have a numeric dimensions, indicating the dimension units - millimeters or inches, punched with a depth to 0.1 mm, without additional chromium or color. Alternatively, the whole design may have an oxidized coating. Non-working parts can be painted with monophonic light paint.

Tip! If the tools allow, choose a set in which the rolling press is equipped with an eccentric planted working conical. In such a device for the brake tubing, a restriction is provided on the size of the fitting of the tube, that is, the cone will not deploy the edge for more than it is necessary, the diameter.

The procedure for action during the collapse of the brake tubes of the fungus do it yourself:

• select the device from the kit for the exact perpendicular trimming of the end of the brake tube, inserting into the hole of the corresponding diameter, we press the screw and turn the cutter a couple of times until it stops;
• there is also an acute semicircular saw for the removal of interior beams and sizards;
• after moving the brake pipe end with a file with a nut-fitting, and fix the end in the clamps, observing the magnitude of the end of the pipe over the plane of the vice;
• we add a couple of droplets to the end of the tube to the tube, insert the mandrel of the corresponding size and the press of the edge of the tube, getting fungus.

Important! With high-quality collapse on the pressed surface of the metal tube there should be no rice or prints of the pisk connector line.

If, according to the collapse conditions, it is necessary to obtain the American version of the fitting, the cone is inserted into the clamp, and the edges of the top of the fungus are pushed under the cone matrix. Sometimes in the design of the clamps are embedded in a ratchet, allowing to limit the force attached to the fitting surface.

If the collapse needs to be performed quickly and in a large number of points, in the case of copper pipes, use a simpler tool - pliers and a rotary roller.

The plasticity and compatibility of copper does not require great efforts to deformation of the metal, so faster and easier to unravel the end of the hand over the brush. Thanks to the compactness of the device, the tongs can be used for the brake pipe flares directly by car, in conditions where the work is difficult to carry out the work of the standard set.

Features of brake tubes

Steel brake tubes, unlike copper, practically do not have a plasticity stock, so fungus and funnels can work out with the formation of a large number of microcracks. In this sense, the fused edge of the fungus remains less sensitive to the presence of microcracks, if, of course, they are only in the area of \u200b\u200bthe opening. If the cracks were formed on the periphery, in the widest place of fitting, this option is unambiguously subject to rejection.

For American double funnels, it is often possible to use only the copper brake tube. In extreme cases, if there is an urgent need for a fading of the steel tube on the US standard, the procedure is performed in two or three stages. In the first stage, after trimming and filing the end of the tube, it is fragmented under fungus. Further, the resulting option is subjected to short-term annealing with a heating burner, which makes it possible to remove a significant part of the stresses in the metal. The third stage will be the roller to the intermediate angle of 25-30 o, instead of the 45 o, and re-annealing. The final fraud is performed under the desired funnel size.

If there is an opportunity, before performing the roller tube, it is worth practicing in obtaining a steel American funnel on an unnecessary trimming of a pipe from a similar material.

The video shows the process of blocking brake tubes:

Independently and will help in repair brake system.

In order to make a rolling for brake pipes with your own hands, you will need:
* Locksmith vice
* Cell slide machine, cutting and grinding circle
* Metal corner size 100 mm
* Metal plate thick 6 mm
* Metal drill with a diameter of 4.5 mm, 6 mm, 10 mm
* Bolt from car hub
* Welding machine, crags, welding mask
* Safety glasses, gloves, headphones
* Copper tube with a diameter of 5 mm
* Metal lathe, equipment
* M6 and M12 thread tap
* Matte paint spray
* Electric drill

Step one.
Press the metal corner with a size of 100 mm in the vice and with the help of a ruler and pencil make the markup, which will need to freeze the workpiece.

We mark from the edge of the corner of about 30 mm and sprinkle with the help of a coal-glare machine with a cut-off circle installed in it. When working with a corner machine, observe security measures, dress safety glasses, headphones and gloves, and also do not forget that the power tool at any time can break out of the hands, so it is necessary to keep it tight.

The brake system of the car is the basis of security and needs professional maintenance. After all, it is from her that the safety of movement by car depends. Today we will tell you about the most terrible breakdowns of the brake system, we describe in detail what kind of braking tubes, for which it is needed and with the help of which tools it is produced.

Brake system malfunctions

Almost all drivers know that the car braking system consists of a control drive, distribution systems and executive (working bodies). All parts of the brake system are connected using brake tubes (highways). According to these tubes, the brake fluid is moved under pressure. In the process of pressing the brake pedal, the pressure on the DW increases and it affects the working body of the system that performs the locking of the wheel and the full stop vehicle.

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

• Violation of tightness brake pipes and pistons in which the fluid is under pressure.
• Mechanical breakdown of working bodies. It is possible to include all sorts of brake cylinders and so on.
• Violation of the free stroke of the pedal. Such a malfunction is discomfort to the driver during the operation of the car.

In this article, it will be discussed precisely about the first fault - a disruption of the tightness of the combustion tubes with working mechanisms.

The brake fluid of the car in its composition contains an acid that adversely affects the thin-leaf metal products. In addition, the constant environmental impact may cause corrosion on metal parts. In this regard, the locations of the brake tubes with the working parts of the system may be subject to corrosion and start producing from the braking system special fluid. Another 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 brake properties of the car.

In order to save money on the purchase of new brake pipes, drivers go to the restoration of the old tube, which passes very successfully. This process was called the collapse.

Rolling brake tubes using a set and device

The collapse is called any deformation or a change in the shape of the tube, which is further fastened to a special product performing a tube connection with a system working body.

This concept refers to the brake system of the car. To make the roller, you need to have a special set for the collapse. It includes a set of devices, such as, cutting device, a deforming device and a set of means for cutting threads on the brake tube.

To carry out the collapse, it is necessary to install a car or overpass and immobilize. From the tank and the main brake cylinder the brake fluid merges. After all the events, it is recommended to replace the new one that in the future it does not climb again under the car. Remove a damaged brake tube fitting from its landing place, and then remove it from the tube itself.

Cut the damaged plot of the highway, about 5 centimeters. To cut the pipe, you need to install it in a special device and go through the blade across the circumference. After that, the cut end of the pipe is processed to get rid of the irregularities capable of disrupting the shape of the pipe, which means its tightness of the compound.

After that, fix the end of the pipe in a special device and insert the roller fungus into it. A thread shaft is put on top of the fungus, which is attached on another fixing device. Rotate the lever occurs a change in the shape of a cut part of the pipe. Then, depending on the presence or absence of threads, it cuts it on the pipe. In most cases, all brake tubes are manufactured without it.

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

Video - How and how to unravel the tips of the brake tubes

On this, the brake tubing is complete. As you can see, it is not a complicated procedure and it will be able to cope with almost any car enthusiast, which will have a set of roller set and other garage inventory.

People who drive a lot are quite quickly starting to be interested in the question of how to unravel the brake tube with their own hands. First of all, it is caused by a completely understandable desire for manufacturers of manufacturers to save: in the former times, copper is used to make these parts, which is much more resistant to aggressive conditions of existence and temperature differences. Now they are set steel, which corrosive where as faster.

The second culprit of the unscheduled wear of the brake pipes should be considered utilities. Chemical reagents and salt, generously scattered for the struggle, for example, with a holler, are at times accelerating metal rust and reduce the life expectancy of many details released by the factory. And the third factor forcing the brakes prematurely - sadly glorified Russian roads.

How to ruin the brake tube with your own hands: the process is pretty simple, but will require the purchase, independent manufacture, renting or leaving the neighbor on the garage of a special device for these works. But if you decide to buy a rolling machine, do not seduce the most cheap options on the market. Yes, you can take the adaptation of rubles for 700-800, but it will definitely be very disposable. The experimental way is established that a more or less high-quality machine cannot cost 1800-2000 rubles or more expensive.

When is it time to change the tubes?

Symptoms that you need to look for a set for ruin, are:

• During emergency braking, when pressed on the pedal, a very characteristic creak is heard;
• Under the same outgoing conditions, rhythmic vibration is felt;
• The brake path of your car is noticeably extended;
• The course of the brake pedal becomes more free, it seems to dangle;
• It is possible to leap the brake fluid (this is especially seen with a sufficiently long parking lot of the car overnight);
• Often observed significant overheating brake drums and premature uneven wear of the pads;
• In indirect symptoms - Lavigating the car of the WBOV during the straight movement.

Rolling and its details

Often the main body in the brake tube remains as a whole, but the structure of its 6-face head is destroyed. There may be other options: coking threaded connections As a result of a liquid hitting them, clogging them, etc. In such situations, if the length allows, you can simply trim the defective part. But it is better to replace the phone completely if there are similar repair. In addition to the collapse machine, mites, pipe cutting, fitting and drill will be needed. From materials - a few acetone.

Responsible motorists know that you need to regularly monitor the condition of your car. Especially keeping the operation of the brake system. Brake tubes play a considerable role. If you have noticed that there are damage on them, then the time to eliminate them. Often there is enough ruin. Do not doubt your abilities, and read carefully an article. Following simple instructions, you will handle the problem without service of the car service.

Purpose and function of brake tubes

Brake tubes are not a separate item, but an important component of a whole system. They create a peculiar highway, according to which the brake fluid is moving. Their good work is required when the speed is reduced, stopping the car and, of course, emergency braking.

The main function of the tubes - ensuring movement working fluid to brake system elements. During this work they are constantly exposed high pressure and hydraulic loads. If they fail, the work of the entire mechanism is disturbed, and the vehicle becomes unsuitable for operation.

When is the brake tubing fragmentation required?

Long-term operation of the car, the ruthless use of the "iron horse", untimely technical inspections and neglect of the rules of care lead to problems, including with brake tubes. They have:

• reduced bandwidth;
• cracks and rust appear;
• weakens or rott fastening;
• sweep thread;
• there is a break.

All this will certainly lead to a failure of the entire brake system as a whole. So, the threat of an emergency on the road will arise.

The correct decision will be the rolling of the tubes, that is, eliminating the directly damaged area. It is not always necessary to change the entire tube entirely. If it allows the length, you can only get rid of the spoiled part. But do not forget the old saying "death seven times, a rejection once."

Reference! The collapse of the brake tubes is used only to metal products. Rubber materials are subject to replacement.

Alarming bells about the malfunction of the brake system, including brake pipes, are:

• leakage of brake fluid;
• foreign sounds, screenshots when you click on the brake pedal;
• uneven wear of pads;
• free movement of brake pedal;
• increasing the brake path;
• overheating brake drums;
• when braking, the car leads to the side.

Important! Ignoring the alarming symptoms can lead both the breakdown of the entire vehicle and the difficult consequences during the movement.

Instructions for self-collaboration

Not every motorist is desired to repair. For some, this is too complex occupation, others have no time and desire. If you relate to the listed categories, you can always contact the car service, and entrust the roller to professionals.

There is another factor that can stop you is the lack of a special tool. Nevertheless, it can always be purchased in the automotive store, or order on the Internet. The tool is most carefully working with metal, while the uniformity of the wall thickness and the smoothness of the inner surface remains.

If you wish, you will easily acquire a set for the collapse. There, in addition to the "Sprelace" includes:

• truboresis;
• ticks;
• clamp;
• fitting;
• stamps for different diameters of tubes.

Important! Do not rush to acquire the cheapest sets. Mostly they are low-quality. It is better to pay a little more expensive, but the life of the tool will be longer.

If the listed obstacles are not frightened, and at hand there is everything you need, do to repair yourself. The process of breakdown brake tubes is not laborious and does not take much time. At the same time, after successfully done work, you will definitely feel a sense of pride from our own opportunities.

Clearly follow the instructions:

1. Bend the car on watching pit or overpass, immobinate.
2. Prepare a set for the collapse, and you will also need a drill and a little gasoline.
3. Unscrew the brake tube from the caliper or brake cylinder. Evaluate the degree of breakage and the ability to repair.
4. If you can remove a spoiled piece, while keeping the desired length, cut it with pipe cutter and throw it away. He has already worked out.
5. Complex edged edge Process with gasoline.
6. Tick \u200b\u200bclamp the tube to create a connector under the fitting.
7. Drill and drill the desired diameter, remove the champecker around the edges of the tube.
8. Clean the tube from the chips and insert the fitting.
9. Take the tool for the roller and insert the tube into the desired hole. It is necessary that its end spoke 5-6 mm per edge.
10. Click the tool. At this time, the mechanism is processed by the desired part.
11. Admire the result of the work. At the end of the tube there should be a neat extension, which hermetically connects the elements of the system.
12. Install all the details in place. Fill the brake fluid and pump the system to get all the air out of it. Test the work of the car.

Pros and cons of the roller tubes do it yourself

The roller process itself will not leave a lot of strength, but, as in any case, you can allocate your positive parties and disadvantages.

The pluses include the following facts:

• you do not need to pay for the work of someone else's people, and this is a profitable savings;
• you are interested in the health of your car, so make a job responsibly and efficiently;
• special knowledge and special skills are not needed, and therefore you will cope with the task;
• you can repair at any time convenient for you, and you will not adapt to the operation of the car service.

The minuses are:

• the need for a special tool for the procedure;
• possibly nonideal execution of the collapse compared with experienced masters;
• undoubted tool after work. It will come in handy only if you regularly deal with used cars.

You can try to repair cars with your own hands, and if you doubt, then trust it by specialists. You decide!

Prevention of brake tubes breakdown

Naturally, in order not to spend a lot of time looking for breakdowns and repairs, it is best to treat your vehicle with care. Do not be lazy, and follow simple tips:

1. Periodically browse the brake pipes for rust and defects. Pollution, microcracks, corrosion lead to incorrect system operation.
2. By regulations, change the brake fluid.
3. Check the tightness of the fasteners.
4. Process the surface with anti-corrosion.
5. Do not allow brake fluid leaks.
6. Become a supporter of a neat ride. There are no cases when the tubes break occurred when overcoming obstacles.
7. Diagnose the brake mechanism at least once every two years. Motorists who spend a lot of time on the road, it is worth doing after every fifty thousand mileage.
8. Regularly follow the wear of the vehicle parts, and it will take care of your safety.
