How to unscrew a brake pipe with torn edges

How to get home if the brake pipe bursts. manipulator Nissan diesel

I started to put everything together when the brake pipe burst. Well, nothing, it was lying somewhere in stock, I began to slowly unscrew it when the brake line burst a little further on.

On the road, the brake pipe burst, and every time the brake pedal was pressed, the fluid leaked out... It was decided to plug the brake pipe - but alas, in vain! Because the pressure is too high, and the tube is rusty..! Another solution turned out to be more practical. Having removed the brake fluid supply hose from the reservoir to the pg, we turn off the rubber hose by inserting a 10mm bolt into it. and tighten it with a clamp so that the bolt does not fly out. And that’s it, you can drive, but carefully, keeping your distance because... The rear brakes don't hold up. PS God forbid that you don’t need this... but maybe it will help someone..!

Device, principle of operation

So, the driver stops the car by pressing the brake pedal. The latter affects the brake force booster, and the latter acts on the GTZ, which compresses the fluid in the lines.

Under the influence of the GTZ force, the liquid is compressed and passes into a zone with minimal pressure. These are tubes, and then - working mechanisms. The brake fluid presses on the drive and the caliper compresses the pads. When the pedal pressure is released, the pressure in the brake booster decreases. Springs in the mechanism release the pads. The liquid moves back into the expansion tank - into the area where the pressure is minimal.

The movement of brake fluid is carried out through copper tubes. The latter are connected to the main brake cylinder and laid along the bottom of the car to the brake mechanisms. The connections of the tubes to the mechanisms and to the GTZ are made in the form of threads - this ensures maximum reliability. After all, the pressure in the line can be quite high.

To increase the reliability of the systems, the tubes are connected to the GTZ diagonally. This makes it possible to use the brake if the latter fails. For example, from the GTZ one of the tubes connects the front left brake mechanism and the rear right one. Another tube directs fluid to the front right and rear left wheels. To ensure that the pressure in the system does not exceed the permissible value, a pressure regulator is installed at the places where all the tubes are connected. In common parlance he is called a “sorcerer”.

Has the brake pedal become wobbly? Broken brake hose? There is a solution!

It just so happens that instead of notes about the desired tuning and modifications to my bus, my entire BZ is filled with articles about repairs. This time there was another breakdown, the rear brake pipe burst. The breakdown could not be repaired immediately, as it burst almost behind the tank. I turned off the circuit on the rear right wheel and drove it like that for 3-4 months. Yes, it’s true that safety comes first, but the car runs every day and there was no time for repairs. Fortunately, the completed technical inspection came to my aid, and I can’t drive without it. The New Year holidays passed, and then I found time to repair my bus. What to do if your brake hose suddenly bursts?

Flaring machine

Of course, if the pipes are faulty, you can take the car to a service station and entrust the repair to specialists. But why spend money on something you can do yourself? To do this, you need to purchase a flaring tool in specialized stores or order it online. It is available for inch or metric threads. The set includes a pipe cutter, a device, pliers, a clamp, and dies for different diameters of tubes for flaring with a fungus.

When purchasing a tool, you should pay attention to the manufacturer and cost. It is better not to buy the cheapest sets, as their quality is not conducive to long-term use. This repair method is less expensive than in a car repair shop, and relatively easy.

Do-it-yourself repair of a rotten brake pipe.

There is one nuance here, the whole point is that you may not have a steel ball at hand; in this situation, you can make a lead ball (if you are a fisherman, you probably carry fishing accessories). You can create something like a ball from cigarette foil. In general, how you will make this same ball is up to everyone, but it will need to be tightly hammered into the vacated hole in the master brake cylinder. Once the ball is hammered into the brake cylinder, you can tighten the brake pipe.

In this video I will tell you in detail how to easily repair a rotten brake pipe. As usual, the pipes rot in the rear of the car and previously it was necessary to replace the entire length of the brake pipe. But I will tell and show, using the example of my car, a 1997 Ford Mondeo 1.8 petrol hatchback, how you can fix a problem like a brake fluid leak for two euros and fifty cents (2.50 euro.). I think everyone can handle this after watching this video. Enjoy watching.

Flaring and its details

Often the main body in the brake tube remains intact, but the structure of its 6-sided head is destroyed. There may be other options: coking of threaded connections as a result of liquid getting on them, clogging them, etc. In such situations, if the length allows, you can simply cut off the defective part. But it is better to replace the tube completely if you are planning to carry out such a repair. In addition to the flaring machine, you will need pliers, a pipe cutter, a fitting and a drill. Materials: a little acetone.

• The required piece of tube is cut with a pipe cutter;
• It is clamped with a holder so that the edge protrudes 5-6 millimeters beyond it;
• Instead of a cone, a stamp is placed that corresponds in cross-section to the tube (both the holes in the holder and the stamps in the flaring device are from 5 to 8, so it is not difficult to select the desired size);
• The inner edge of the tube is cleaned with something sharp; an ordinary knife will do;
• The end is slightly straightened with a file;
• The fitting is put on exactly at this moment, since later it will no longer be possible to tighten it. The thread of the nut should be directed towards the end of the tube, not towards its body;

• The stamp is screwed in, flattening the end of the tube. The main thing here is not to overdo it and not to flatten it too deeply;
• The next step is not necessary - the European fastening standard has been met. However, the American standard, also called double cone, is considered more reliable. If you're looking for strength, get started. The stamp is removed; a cone is placed instead. It must be screwed in gradually, carefully and without distortion;
• The result should be a tube ringed with a nut with a smooth mushroom-holder at the end, if you stopped at step 7, or a recess in the cap, if you went further;
• The finished tube is installed in place of the failed one, brake fluid is poured into the system, then passed through it. The vehicle and system are checked for the absence of the above-described signs of problems.

Having figured out how to flare a brake pipe with your own hands, provide yourself with a minimum of such work in the future: place the copper one in the designated place. We assure you: you will have to remember about flaring much less often. Even with very intensive use of the machine, you will not need it before 2-3 years.

Hello to all DIY lovers. In this article I will talk about how to make rolling for brake pipes with your own hands. This device will be useful for those who service their car themselves and will help in repairing the brake system.

Before reading the article, I suggest watching a video that clearly shows the assembly process of this device, as well as testing it in real conditions.

In order to make rolling for brake pipes with your own hands, you will need:

* Bench vice * Angle grinder, cutting and grinding wheel * Metal corner measuring 100 mm * Metal plate 6 mm thick * Metal drill with a diameter of 4.5 mm, 6 mm, 10 mm * Bolt from the car hub * Welding machine, leggings, welding machine mask * Safety glasses, gloves, headphones * Copper tube with a diameter of 5 mm * Metal lathe, equipment * Tap with M6 and M12 threads * Matte spray paint * Electric drill

Step one.

Clamp a metal corner measuring 100 mm in a vice and, using a ruler and pencil, make markings along which the workpiece will need to be sawed off.

Replacing brake pipes. Important points!

But to be honest, there was a situation: I waited until the ordered parts were delivered, during which time I turned off the brakes of both rear wheels and drove CAREFULLY for a week. Both wheels need to be turned off (although I also had a problem with the right rear). Replacing brake pipes. Useful tips! https://youtu.be/UNJteTLdH5Q In this video I tried to tell and give some useful tips on replacing brake pipes using the Passat B3 car as an example. But all this applies to other cars. Let me remind you that you should not wait for the brake pipe to become very rusty and burst. Inspect the brake pipes in a timely manner and replace them with new ones if required. Do not wait for the brake pipe to burst at the “hour X”.

Reasons for tube failure

As a rule, on most cars, the brake line becomes unusable due to corrosion. It is not uncommon for old pipes to develop cracks. Brake fluid then slowly leaks out of these cracks. The tubes are made of copper and, it would seem, should not corrode, but this is not the case. Corrosion eats up highways, and we also need to add to this the negative influences of the external environment. The environment has a particularly negative impact on the metal of pipes in winter, when utility services spray roads with caustic reagents.

Also, one of the reasons for failure is poor fastening of the line to the body. Often the line is fixed to the bottom of the car and is not protected by anything. In winter, the bottom of the car can catch various obstacles and as a result the tube cracks or breaks. Also, if the element constantly moves along with the body, then over time a kink appears at the place where the line bends. The part is easily damaged.

Is it unacceptable even temporarily? I plugged it with a toothpick, covered it with superglue and liquid nails and went to the city to look for the pipe.. I rode around for half a day and seemed to be alive))) And then you write that it’s not acceptable. and to Moscow 120 km. After all, I at least need to get to Moscow!

Where to look for these refrigerators? Then you will probably have to remove it because it will burst into flames when sealed?

Can you imagine what pressure is in the brake system? Master, I wouldn’t do that to myself.

Added after 1 minute 15 seconds: If the clamp was wide and made of tin, this would be at least something, but a sharp braking would cause the whole thing to fall off.

for a long time now in almost any car market, there is a place where brake pipes are made, they are made right on the spot, there are catalogs of fittings and lengths, but you can bring an unscrewed fitting and name the approximate length, the price is 20-30 rubles per fitting and 120-250 rubles per meter of tube together with work, depends on the greed of the seller, I recently replaced the two longest lines that go back above the tank + I replaced several short ones on the rear beam. It burst when leaving the garage. I also changed one front pipe on the car in winter, no problems.

Instead of covering it up, to get there, it’s better to bend the end of the tube several times and flatten it with a hammer, plugging it and changing it when the opportunity arises.

If I were you, I wouldn’t do pornography with cold welding, but would just solder it. Once, guaranteed and forever. The same pos 40 solder with a melting point of 183–238 °C, which is available in all stores. Just first treat the soldering area with flux for low-temperature soldering of aluminum (costs 150-300 rubles, depending on the volume), which is also widely used. At least you will be sure that the sealant will not fall off one fine day.

Emergency situation

Tubes and hoses that connect individual elements of brake systems (so-called brake lines) are needed to transmit forces. The system contains a special working fluid (it is the carrier of energy), which transmits force from the brake pedal to the master cylinder, and only then the force goes to the working cylinders. In general, piercing tubes is rare, but connecting nodes can indeed leak - this is not very uncommon. Often, a car enthusiast only needs to inspect the hydraulic circuit after first lifting the car or driving it into an inspection hole. Experts confirm that inspection and diagnostics of car brake systems should be carried out every 50 thousand kilometers. Individual elements of the circuit must be replaced at certain intervals.

It is important to note that there are two circuits in the brake system. One is the main one, and the other is a backup one. Usually both circuits work, but if one fails, the second will take over all its work. Due to this, the likelihood of a situation occurring when the entire braking system fails is reduced significantly. But how can you understand that there is a problem with the brake pipes without contacting a specialist? Here you need to pay attention to the following:

• The brake drums began to heat up more than usual;
• There is a brake fluid leak;
• Upon inspection, it was revealed that the brake hoses began to become covered with cracks;
• Uneven wear of the installed brake pads is observed;
• The brake pedal has a large free play;
• When pressing the brake pedal, the driver hears a squeak and feels a pulsation;
• The braking distance of the car has increased significantly.

In most cases, brake lines simply become obsolete. Original tubes are usually metal, and metal does not last very long, because sooner or later it will begin to suffer from corrosion. Tubes wear out especially quickly in winter, when roads are covered with salt, a substance that accelerates the destruction of metal. Additionally, impacts from rocks, gravel, and branches from the road can damage the tubes. It is impossible not to note the importance of proper installation of tubes. If the fittings are overtightened, the tubes themselves are not fixed correctly or are severely broken in several places, they will wear out faster.

Using cold welding to repair a car

The article will tell you about cold welding for a car, how with the help of such an easy-to-use tool you can carry out high-quality repairs of your iron friend.

During the operation of the vehicle, there may be a need for emergency body repairs. For example, while driving along the highway, a car’s gas tank or radiator may break.

It is clear that in this situation you will not be able to carry out a full-fledged car repair and you will most likely not carry a welding machine with you. In addition, it is not always possible to rely on the help of a tow truck, that is, it may seem that in these cases you will find yourself in a very difficult situation.

But, if your car’s repair kit includes cold welding, then you can deal with all the troubles yourself and in a short period of time. In this regard, let's look at what cold welding is and how to use it.

What is cold welding

Cold welding is a special repair kit with which you can do the same work as using traditional welding. That is, seal the holes, restore the strength of the seams, and attach the metal parts to each other.

You can buy such a product at an auto store or hardware store. There is a special cold welding for the car, which is an epoxy resin-based glue. And with its help you can repair any damage to the radiator, gas tank, engine crankcase and much more with your own hands.

Today, there are many manufacturers of this product and all of them are of high quality, so there will be no problems with the choice of cold welding.

How to use cold welding when repairing a car

So, what exactly tools are needed for this: cold welding, sandpaper (fine-grained), acetone or pure gasoline.

1. First of all, you need to prepare the surface for repair. For example, if we are talking about repairing a broken gas tank, then the repair site should be cleaned with sandpaper. It will be good if you make irregularities on the prepared surface, for example, make scratches or other roughness - this is necessary for better adhesion of the weld to the surface.

2. Next, degrease with gasoline or acetone; this procedure is also important.

3. Now the time has come to prepare the glue: take cold welding to repair the car, carefully read the instructions.

Using damp hands (you need to moisten them), you need to cut off or squeeze out (depending on the type of product purchased) the recommended part of the glue and knead it until the required homogeneity and plasticity. The resulting mixture will even warm up a little, you will feel it through your hands.

4. Now we apply the composition to the prepared area; all actions must be performed quickly, because there are adhesives that polymerize very quickly. We sit and smoke, waiting for the welding to set - this can happen from 40 minutes to a day. Such a difference in time occurs from many factors: the manufacturer of the product, street temperature, thickness of application, and more.

Thus, you get a strong and tight connection that will serve you for a long time. But, after the repair, the appearance of the gluing is not attractive.

It is clear that if we are talking about repairing the bottom of the gas tank, then this is not important, but if you are repairing the body, then after welding the following work should be done. After welding is completed, the surface is cleaned with sandpaper, then primer and paint are applied. Of course, if you look closely, traces of repairs will be noticeable, but this is better than driving with holes in the body.

Here you can watch a video where a man went to relax in nature and punctured the engine crankcase, but thanks to cold welding, he rested and got home in his car.

So the conclusion is simple, always carry with you such a useful and sometimes necessary thing as epoxy resin glue.
