The disk brake mechanism of back wheels

Except for the model capacity of 66 kw which have been not equipped АБС, 92 let out till October, on the back bridge are established disk brake mechanisms instead of the drum-type. It is a question, as well as in a case with brakes of the forward bridge, about disk brake mechanisms with floating bracket.

In addition to a hydraulic drive through a brake pedal the disk brake mechanism can be served also тросовым by a drive of system of a lay brake. The lever on which the corresponding cable is fixed, puts in action a pusher which the brake piston nestles to колодкам.

Automatic control

Designs of disk brake mechanisms in the car are always carried out by the self-regulated: with increasing deterioration brake pads the brake piston simply leaves further a support of the disk brake mechanism, providing with that dense прилегание brake pads to a brake disk. Owing to filling of the added volume in the cylinder a brake liquid formation backlash is impossible.

On another it occurs in a mechanical drive of lay brake system: here press the drive pusher at some instant time simply could not get the coming to light piston if there was no adjusting device. It "extends" a pusher as required. The basic part of regulation is a carving, on which depending on deterioration pads all further forward наворачивается a pusher part. The press device thus becomes longer. Therefore at replacement pads it is impossible to push simply back the brake piston, it turn off back on the adjusting device.
