Before you start: Clean the caliper from dirt.
1. Remove the edge of the protective cap from the cylinder groove.
2. Turn the cap inside out and remove it from the piston.
3. Install a wooden spacer (so as not to damage the piston), supply compressed air into the cylinder through the fluid supply hole. The piston will come out of the cylinder.
4. Remove the wooden shim and take out the piston.
5. Carefully remove the sealing ring so as not to damage the cylinder mirror.
6. If necessary, unscrew the air release valve.
7. Remove the sealing ring from the valve.
8. Thoroughly clean all dirt from all parts of the wheel cylinder and rinse with clean brake fluid.
9. Inspect the cylinder mirror. If there are deep grooves, scratches, roughness, etc., replace the cylinder.
10. Inspect the cylinder piston. If there are deep grooves, scratches, roughness, etc., replace the piston.
11. Regardless of the condition of the sealing ring, replace it with a new one.

13. Replace a cracked, torn or loose valve seal or a valve with damaged threads.
14. Assemble the cylinder in the reverse order of disassembly, lubricating all parts with brake fluid. Before installing the piston, put a protective cap on it, inserting its edge into the piston groove.
