A good brake cylinder is a guarantee of safety on the road

Among the systems of the car, each of them plays a huge role in the process of its movement. But there is also inhibition. For this, there is a brake system. The simplest brake system includes a master brake cylinder, connecting pipes, connecting hoses, calipers, pads and brake discs with drums. Naturally, the state of each body must be constantly monitored, since the operation of a vehicle with a faulty braking system is prohibited even to the repair site, so it is written in the rules of the road. This is logical, because it is simply dangerous.

In addition to the main, there is also a service brake cylinder, which is used only in drum brakes. It has a two-way action, that is, the pistons diverge from the center to the edges. According to the principle of equal pressure, they exert equal effort on each shoe.

The main brake cylinder VAZ has two chambers, since the braking system is a two-circuit brake. This scheme is very convenient, because, if the brakes on the front wheels fail, the rear ones will function, and vice versa. In addition, repairs are facilitated, since full pumping of the brakes is not required , say, in the case of a rupture of the hose to the front caliper. Naturally, the piston in this case has a two-sided shape in order to pressurize both circuits.

The main brake cylinder UAZ includes the tanks for the brake fluid, they are fixed directly on it. There are two of them, because the system is the same, dual circuit. This design is quite convenient, because these tanks do not require additional space, but there are cases of their breakage, then their remaining thread is problematic to withdraw from the steel case.

The main brake cylinder has a fairly large service life, especially if the brake fluid and rubber seals are changed in time. Why do I need to change the brake fluid? The fact is that over time it loses its properties and becomes compressible. This reduces the efficiency of braking. As for rubber seals. They, as a rule, have the form of rings, and they need to be changed at the first leakage of the brake fluid. Firstly, this can be learned by reducing the braking force, and secondly - periodically inspect the car for such leaks, not only in the braking system.

So, if such a leak still occurred, then it must be immediately eliminated, since in this case the pistons begin to wash the steel surface with a cylinder mirror, then it can not be restored, the brake cylinder needs to be changed. This applies not only to the main, but also the working cylinders.

A common drawback of the brake system is the wear of the faces on the nuts securing the tubes. They are tightened quite strongly, then they are affected by an aggressive environment, so that they can not be unscrewed with a simple locate key. To do this, there are special spanner keys, which it is better to carry out such an operation. In addition, you need to ensure that the nut gets into the thread, because otherwise you have to change both the tube and the node into which it is screwed. Here are the main points that you need to pay attention to when using the brake system of a car. Of course, there are other situations, but they appear due to neglect of the data.
