CheckLift the car and establish on supports, remove back wheels.
On cars with back drum-type brakes checking of thickness of blocks is a part of procedures of periodic service.
On the cars equipped with back disk brakes, remove disks. Take a support aside and fix a support a wire, a tube of a brake do not disconnect.
Check a condition of all details of the hand brake, existence on them of wear and damages.

However, they can wear out owing to the wrong adjustment of brake system, or because of regular use of the hand brake for a car stop. The limiting size of wear of blocks of the hand brake is not normalized, however it is recommended to change them, if residual thickness of blocks less than 1,5 mm. Check a condition of springs and the regulator mechanism, and also check a drum condition, existence on it deep development of scratches and other damages.
