GENERAL INFORMATION

On the models described in this management the hydraulic double-circuit brake system with division on lobbies and back wheels is installed. On forward wheels disk brakes, and on back - drum or disk, depending on model are established. Both forward, and back brakes are self-regulating. Disk brakes are automatically regulated depending on wear of brake shoes, and drum brakes have the adjusting mechanism which is put in action at statement of the car on the emergency brake.

Hydraulic system

The hydraulic system consists of two contours. The main cylinder of brake system has two tanks for two contours and, in case of leak of brake fluid or an exit of one of contours out of operation, the second contour will work. The double valve of restriction of pressure which is installed on a back wall of a motive compartment, provides balance in braking force between lobbies and back brakes. On models on which the system of anti-blocking of brakes (ABS), the valve of restriction of pressure sensitive to car loading is installed limits pressure in a contour of back brakes depending on car loading.

Vacuum amplifier

The vacuum amplifier uses a difference between pressure in an inlet collector of the engine and atmospheric pressure for strengthening of brakes. It is established on a back wall of a motive compartment.

Emergency brake

The emergency brake involves only back brakes. The drive is carried out by means of ropes. The car is put on the emergency brake by means of the lever installed on the central console.

Service

After dismantling any of elements of brake system, it is necessary to check work of brake system before normal operation of the car. When checking brakes, carry out control braking on an equal, dry, flat surface. Carrying out check in other conditions can yield incorrect results.

Check work of brake system at various speeds and with various force of braking. Braking has to be uniform and the car should not pull in any party. Try not to block brakes as it leads to sliding of the car, reduces efficiency of braking and controllability of the car.

Quality of tires, loading of the car and adjustment of wheels are the factors which are also influencing work of brakes.
