Master cylinder parts
1 - body; 2 - lock washer; 3 - fitting; 4 - gasket; 5 - cap; 6 - retaining ring; 7 - pusher piston; 8 - sealing ring; 9 - the piston of the main cylinder; 10 - spring
1. Unscrew the plug, remove the protective cap 5 of the cylinder body and the retaining ring 6. This will allow you to remove the piston 7, the sealing ring 8, the floating piston 9 with the sealing ring and the return spring 10 of the piston from the body.
2. The cylinder mirror and the outer surface of the piston must not be damaged or scratched. The inner diameter of a serviceable master cylinder should be 19.05+0,025–0,015 mm.
3. Check the condition of the piston return spring and replace it if it has lost elasticity.
4. Replace o-rings.
5. Check the protective cap on the rear end of the cylinder and if the cap is damaged, replace it with a new one.
6. Carefully clean and flush parts with brake fluid before reassembly. Keep parts away from mineral oil, gasoline, kerosene or diesel fuel as these substances swell rubber seals.
7. After checking all parts, assemble the master cylinder in the reverse order of disassembly; moreover, lubricate all parts of the cylinder with brake fluid or NG-213 preservation fluid.
