21.1. General information

To destination and to the carried-out functions the brake system is divided on working, spare, parking and emergency. The working brake system with necessary efficiency provides regulation of speed of the car and its stop. The spare system serves for a car stop at failure of the working brake system. The parking system serves for deduction of the car not movably on the road. Generally use it for deduction of the standing car, but it is possible to apply also as the working brake system, emergency at failure.
On the car the working brake system with the hydraulic drive and diagonal division of contours is used that considerably increases safety of driving of the car. At refusal of one of contours as the spare brake system the second contour providing a car stop with sufficient efficiency is used.
In the car the disk ventilated brakes on forward wheels and ventilated or with a continuous brake disk – on back are used.
The hydraulic drive of brakes is equipped by the amplifier of brakes.
The tank with brake fluid which is in a motor compartment over the main brake cylinder supplies the brake system and coupling with brake fluid. The vacuum amplifier of brakes reduces effort to a brake pedal, facilitating thereby driving.
The parking brake influences back wheels via the hummock drive.
