Ford Focus>> Brake system>> Brake bracket and pistons of brake cylinders>> Check of pistons of brake cylinders
Check carry out as follows:
- before you will check a free wheeling of the piston of the brake cylinder, put as an emphasis a clamp with wooden slips in a bracket. So the piston will be protected from damage — it cannot leave the cylinder entirely. The slip on the other side of a disk should be established;
- ask your assistant to press a brake pedal carefully. If the piston jammed, strengthen pressure upon a pedal. If the piston moved out from a place, return it back by means of an assembly shovel. Repeat procedure until the piston will easily not slide in the cylinder;
- if the piston does not move, replace a bracket.
