Removal and installation of the wheel brake cylinder

If it is not necessary to change the wheel brake cylinder, it can be removed assembled. In any case, the first step is to remove the brake pads. Wheel brake cylinders should be repaired at the latest when there is a brake fluid leak. To check, you need to remove the anthers and look into the cylinder. If it is wet behind the boot, or the entire cylinder is covered in brake fluid, it should be repaired. Repair is also required when there is no easy piston stroke in the cylinder. In one of these cases, the wheel does not brake during braking, or brakes constantly.

Caution: The grooved cylinder must be replaced.
