10.11. Adjustment of the hand brake

Cars with back drum-type brakes

Adjustment of a cable (cables) on the cars equipped with back drum-type brakes, is necessary only after cable replacement, or after a cable detachment from a back brake for any reason. If the car is not kept by the hand brake, usually it indicates or wear of brake shoes, or on malfunction of the mechanism of adjustment of a gap between blocks and drums.

1. Lift a back part of the car and establish on supports.
2. Completely lower the lever of the hand brake, then several times press a brake pedal.
3. Lift the lever of the hand brake up on five clicks.
4. Equally tighten or weaken adjusting nuts until then while back blocks will concern hardly a brake drum. And you should feel that wheels rotate with identical resistance.
5. Release the hand brake and be convinced that wheels freely rotate. Otherwise adjustment repeat.
Cars with back disk brakes

On cars with back disk brakes the mechanism of self-regulation of a gap between blocks and drums is absent. Therefore to compensate wear of blocks, the hand brake is required to be regulated periodically. Adjustment also should be carried out every time after replacement or removal of a cable, a brake disk, or the mechanism of the hand brake assembled for any reasons.

6. Slowly lift the lever of the hand brake, count up number of clicks. If the lever can be lifted above the eighth, adjust a cable of the hand brake as it is described below.
7. Remove a cover of the hand brake. On some cars removal of the central section (tray) can be necessary for access to the mechanism of the hand brake.
8. Release on one bolt on each back wheel. Lift the car and establish on supports.
9. Unscrew each released bolt. Highlighting a small lamp, turn a wheel until then while in an opening for a bolt you will not see a regulator cogwheel.
10. Rotating a regulator wheel on hour or counter-clockwise, dissolve brake shoes so that they concerned a brake drum. Take away blocks so that wheels freely rotated (on 3 or 4 teeth on a regulator).

If the cogwheel of a regulator is hardly turned, remove wheels and a brake disk, then grease a regulator and repeat adjustment.

11. After disk installation three times turn on the hand brake, then slowly lift the lever of the hand brake up before the fifth click. Equally rotating adjusting nuts achieve, that blocks hardly touched drums and that wheels rotated with identical resistance.
12. Release the hand brake and check that back wheels freely rotate.
13. Tighten bolts of wheels with the set moment.
