9.8.1. Check of efficiency of operation of the parking brake
SEQUENCE OF WORKS
1. Stop the car on a small bias and allow it to slide from it freely. Easily press a pedal of the parking brake. At the same time the parking brake has to work, and the car should not accelerate.
2. Press a brake pedal stronger, before blocking of back wheels.
3. If the sufficient brake effect is impossible even after five clicks of a pedal of the parking brake, at least adjustment is necessary.
4. The big free wheeling of a pedal of the parking brake indicates wear of overlays of brake shoes. If at the parking you regularly strongly tighten the parking brake, the big free wheeling of the lever can also be a consequence of the extended driving cables.
