The brake system of a car is practically the most important in its composition, and it plays a key role in driving safety. We rarely notice the work of the brakes, because they have become as common to us as, for example, a TV, refrigerator or other objects that surround us in everyday life. This system requires complete sealing to function properly, which is ensured by venting the conductive tubes and hoses.
In this article, we'll take a quick look at how to bleed your brakes. This process is quite laborious, therefore it requires certain skills, as well as tools. First, let's talk about the theoretical side of the issue. We all know that the unique property of liquids is their incompressibility, it is this that is used as the basis of the entire system. So, when you press the pedal, we push the piston, which is located in the master brake cylinder. Tubes depart from it, through which the brake fluid under the pressure of the piston moves to the calipers and to the workers.cylinders. This pressure, it must be said, sometimes reaches 3 MPa. After entering the caliper or working cylinder, the fluid transfers pressure to the piston, and it, in turn, to the brake shoe.
Now consider how to pump the brakes in practice. In general, there are many ways. For their implementation, various devices are used that allow you to pump the brakes alone. Let's start simple. The very first method talks about how to bleed the brakes with an assistant. This does not require a lift or other sophisticated equipment. First you need to fill the tank located above the master brake cylinder. Now we need to start with the farthest wheel. The assistant should make several clicks on the pedal - this will create pressure in the system. Now a hose is put on the caliper fitting, and it is unscrewed. Then it is twisted (all this happens with the pedal depressed), after which the procedure is repeated until air bubbles no longer enter the hose. Next, move on to another wheel of the same axle. With it, we carry out all the described actions and move on to another axis. At this time, you should constantly monitor the level of liquid in the tank. This is one way to bleed the brakes.
Let's consider another one. He will tell you how to do it yourself. Bleeding the brakes without a helper is not that difficult, only it takes a little longer and requires more brake fluid.
The car must be installed on a hill,it would be better if it was a lift. Next, one end of the hose must be put on the fitting, and the second on the vacuum container. A pear with a volume of 250 ml will perfectly cope with this role. Now we unscrew the fitting, after which we make a few clicks on the pedal. Here you need to constantly monitor the vacuum. If it is not there, then the air will go back into the system, and everything will have to be done again. With other wheels, the procedure is the same.
Here are two main ways that can come in handy when bleeding the brakes. In addition, it is worth remembering the harmfulness of brake fluid and thoroughly wash your hands after work. It is undesirable to do all this in rubber gloves, because rubber melts under the influence of such a liquid, there may be burns.

"Gazelle" - perhaps the most popular light truck in Russia. Since this machine is constantly under load, it is important to monitor the condition of all components and assemblies. This is especially true for the brake system. Safety depends on her work. From time to time on this car it is necessary to pump the brakes. How to do this, we will consider in our today's article

In the article we will talk about how to pump the brakes on the "Niva" with our own hands. To do this, you can use one of the methods - with a partner and without him. Of course, it is much more efficient and reliable to use the first method. It is he who is usually given in the manuals for the operation of cars. Almost all passenger cars use the same algorithm for bleeding the brake system. Let's first look at the design of the brakes and decide when it is required

Bleeding the brakes on the VAZ-2107 with and without an assistant
When pumping the brakes on the VAZ-2107, you must strictly follow the sequence. However, this must be done with such maintenance of any car. The most important thing is to move when pumping from the farthest brake mechanism to the nearest one (relative to the main brake cylinder). In other words, if the GTZ is in the VAZ-2107 opposite the driver, the first step is to pump the mechanism of the right rear wheel. And last but not least, the front left
