Caution! 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 the removed parts and to the inner wall of the cylinder.
Take care not to scratch the piston or the inner wall of the cylinder.
Tighten the brake lever pivot bolt and the locknut.
