Master Cylinder Assembly

Before assembly, clean all parts including the master cylinder with brake fluid or alcohol.

NOTICE

Except for the disc pads and disc, use only disc brake fluid, isopropyl alcohol, or ethyl alcohol for cleaning brake parts. Do not use any other fluid for cleaning these parts. Gasoline, engine oil, or any other petroleum distillate will cause deterioration of the rubber parts. Oil spilled on any part will be difficult to wash off completely, and will eventually deteriorate the rubber used in the disc brake.

Apply brake fluid to each parts and the inner wall of the cylinder.
When installing the piston assembly, take care not to scratch the piston or the inner wall of the cylinder.
Apply silicone grease to the followings.
