The lever of the parking brake through hummock drafts puts in action brake mechanisms of back wheels . As drafts the steel cable in a flexible, twisted braid is used. Wear of the parking brake is in use insignificant. Usually adjustment of the parking brake is not required, thanks to work of system of self-regulation of brake disks.

Adjustment of the parking brake make at serviceable working brake system in the following cases:

- after replacement of cables of a drive of the parking brake;

- after replacement of brackets of the brake disk mechanism;

- after replacement of brake shoes or brake disks;

- at a big course of the lever of a lay course.

Prevention The hummock drive and all mobile elements of lay brake system should have an easy course, and back brake mechanisms of working system are adjusted.

Adjustment of the parking brake carry out in the following order:

- several times with force press a pedal of a brake and release it;

- lower the lever of the parking brake in the bottom situation;

- raise and expose on a support a back part of the car;

- tighten an adjusting nut (fig. 310) near the equalizer until the rychazhok of the hand brake on a back brake support will not move from an emphasis (fig. 311) . The formed gap can make to 1 mm;

- establish the lever of a drive of the parking brake in extreme top situation and again lower it. Check, whether wheels freely rotate. Overlays of brake shoes should not rub about brake disks;

- establish the lever of a drive of the parking brake on 3 — 6 clicks and be convinced that wheels in this case are not turned.

If traction cables of a drive do not provide a due tightness of all brake mechanism, in this case adjustment of the parking brake carry out in the following order:

- completely weaken a regulator (see fig. 310 ) the parking brake until rychazhka of the parking brake on back brake supports will not depart back against the stop;

- draw opposite to each other two small lines — one on a rychazhka of the parking brake, and another on a back brake support;

- slowly tightening a regulator of the parking brake, watch rychazhka of the parking brake which should rise. When the distance between labels will make about 1,0 mm, establish the lever of a drive of the parking brake in extreme top situation that the tension of cables of a drive of the parking brake was leveled;

- again check the provision of rychazhok on both brake supports of back wheels. If it remained the same, tighten a regulator of the hand brake;

- establish the lever of a drive of the parking brake on 3 — 6 clicks and be convinced that wheels in this case are not turned;

- establish the lever of a drive of the parking brake in extreme top situation and again lower it. Check, whether wheels freely rotate. Overlays of brake shoes should not rub about brake disks.
