Check the condition of the piston return spring and replace it if it has lost elasticity.
Replace the sealing rings. Check the protective cap on the rear end of the cylinder and, if the cap is damaged, replace it with a new one. Before assembly, carefully clean and rinse the parts with brake fluid. Do not allow mineral oil, gasoline, kerosene or diesel fuel to come into contact with the parts, as these substances will swell the rubber seals.
After checking all parts, assemble the master cylinder in the reverse order of disassembly; and lubricate all parts of the cylinder with brake fluid or NG-213 preservation fluid.
