According to the destination and to carried-out functions the brake system is divided on working, spare, lay and emergency. The working brake system provides regulation of speed of the car and its stop with necessary efficiency. The spare system serves for a car stop with necessary efficiency at failure of the worker of brake system. The lay system serves for car deduction motionlessly concerning the road. It generally 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 increases 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 and disk brakes on forward and disk or drum-type brakes on back wheels.
The tank with brake liquid is in a motor compartment over the main brake cylinder and supplies brake system and coupling brake liquid. The vacuum amplifier of brakes reduces effort on a brake pedal, facilitating thereby driving.
The brake mechanism of a forward wheel disk with a mobile support. It is well entered in a wheel, has a small amount of details, including consolidations, and small weight. As heatreturn occurs via one cylinder, brake liquid heats up less.
The hand brake influences back wheels through a hummock drive.
Prevention
At work of brake shoes the brake dust which contains asbestos is formed, unhealthy therefore when cleaning brake shoes do not use the compressed air and do not inhale a dust.
At movement on the 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 remains of rubber, greasing and dirt which reduce efficiency of braking. At a car stop after movement in the rain at the end of movement it is recommended to dry brakes in pressing a brake pedal.
After installation of new brake shoes they should be earned extra. On the first 200 km of run it is not recommended to make the maximum braking needlessly.
Korrodirovannye brake disks cause vibrating effect which does not disappear at long braking when braking. In this case brake disks are subject to replacement.
The brake liquid used in hydraulic system of brakes, is poisonous, therefore at its hit on skin it is necessary to wash out immediately this place a large amount of water. If liquid on imprudence got to eyes or in an organism, it is necessary to address immediately to the doctor. Some liquids have property easily to ignite and can light up even from contact to hot knots of the car. Besides, brake liquid dissolves paint and plastic therefore at liquid hit on a paint and varnish covering of the car, wash out it a large amount of water. Also this liquid is hygroscopic, that is absorbs moisture from air and consequently the liquid, being stored in open ware, it is not recommended to use a long time.
Brake liquid should not contact with mineral oils. Even a small amount of mineral oil puts out of action brake liquid and brake system.
Replacement of brake liquid make each 2 years.
