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

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

In addition to the main one, there is also a working brake cylinder, which is used only in drum brakes. It has a double-acting, that is, the pistons diverge from the center to the edges. By the principle of equal pressure, they apply equal force to each shoe.

The main brake cylinder VAZ has two chambers, since the brake system is dual-circuit. Such a 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 a complete bleeding of the brakes is not required, for example, in the event of a hose rupture to the front caliper. Naturally, the piston in this case has a double shape in order to pressurize both circuits.

The main UAZ brake cylinder also includes brake fluid tanks, they are fixed directly on it. There are two of them, because the system is the same, two-circuit. This design is quite convenient, because these containers do not require additional space, but there are times when they break, then it is problematic to remove their remaining threads from the steel case.

The main brake cylinder has a fairly long service life, especially if the brake fluid and rubber seals are changed on time. Why change brake fluid? The fact is that over time it loses its properties and becomes compressible. This degrades braking performance. What about rubber seals? They are usually ring-shaped and should be replaced at the first leak of brake fluid. Firstly, you can find out about this by reducing the braking force, and secondly, periodically inspect the car for such leaks, not only in the brake system.

So, if such a leak did occur, then it must be immediately eliminated, because in this case the pistons begin to erase the cylinder mirror with a steel surface, it cannot be restored later, the brake cylinder must be changed. This applies not only to the main, but also to the working cylinders.

A common drawback of the brake system is wear on the edges of the tube nuts. They are tightened quite strongly, then they are exposed to an aggressive environment, as a result of which it is impossible to unscrew them with a simple open-end wrench. For this, there are special ring wrenches, which are better to carry out such an operation. In addition, you need to make sure that the nut gets into the thread, because otherwise you will have to change both the tube and the assembly into which it is screwed. Here are the main points that you need to pay attention to when operating the brake system of the car. Of course, there are other situations, but they appear due to the neglect of data.
