THE GENERAL DATA

According to the destination and to carried out functions the brake system of the car is subdivided on working, spare, lay and emergency. The working brake system provides regulation of speed of the car and its stop with necessary efficiency. Spare serves for a stop of the car with necessary efficiency at failure of working brake system. Lay serves for car deduction are motionlessly rather expensive. To it basically use for deduction of the standing car, but it can be applied and as emergency at failure of working brake system.

On the car the working brake system with a hydraulic drive and diagonal division of contours is applied that considerably raises safety of driving of the car. At refusal of one of contours as spare brake system the second contour providing a stop of the car with sufficient efficiency is used.

The brake system consists of the main brake cylinder, the vacuum amplifier of brakes, disk brakes on forward wheels and drum-type or disk brakes on back wheels.

The vacuum amplifier of brakes reduces effort to a brake pedal, facilitating thereby driving.

The regulator of pressure of back brakes is located in a hydrodrive on each back brake. On the majority of models pressure regulators are located separately, but on some models with back brake drums pressure regulators are united with back working cylinders.

At movement on damp road it is recommended to press from time to time a brake pedal to remove from brake disks harmful inclusions. At the expense of centrifugal force water at movement is dumped from brake disks, however, on them there is a thin film from fats, силиконов, the rests of rubber, greasing and a dirt which reduce efficiency of braking.

After installation new brake pads they should be earned extra. On the first 200–300 km of run it is not recommended to make the maximum braking needlessly.

Корродированные brake disks cause vibrating effect which does not disappear at long braking at braking. In this case brake disks are subject to replacement.
