Adjustment of the parking brake

The parking brake is completely independent of working brakes of the car. Therefore wear of blocks of the parking brake is insignificant. As a result of corrosion of the brake drum or pollution of brake shoes the brake moment decreases. If old blocks are regulated, the parking brake has to be earned extra previously. For this purpose carefully tighten the parking brake at a speed of 40 km/h so that action of a brake was slightly felt.
Keeping movement speed, tighten a brake on one tooth and pass 400 more m. Release a brake and let's it be cooled. Thus the rust which can be formed on a frictional surface, and wear products is removed.

Adjustment of the parking brake is necessary at:

- To replacement of brake shoes
- To replacement of brake drums / back brake disks
- To installation back adjusting device.
- Too big way, passable lever of a brake (over 10 teeth).
- To replacement of a cable of the drive of a brake

Cables of the drive of the parking brake and all mobile elements of a brake have to have the easy course.
