We remove the main brake cylinder for repair, as well as for replacing the vacuum booster. As practice shows, repairing the brake master cylinder does not give the desired result, so it is better to replace it
Defects of the main brake cylinder, in which it should be repaired or replaced:
- - contamination of the main cylinder or heavy wear of its mirror;
- - wear or damage to the master cylinder piston cuff;
- - cuff swelling;
- - compensation holes are clogged (the car brakes spontaneously)
In the article, we will consider the replacement of the reservoir of the brake master cylinder and the master cylinder itself
Of course, we rarely replace the tank, but sometimes you need to remove the tank to flush it.
This is especially necessary before changing the brake fluid, when the walls of the reservoir become dirty and there is no way to rinse it without removing it.
