Periodic Maintenance Procedures
Master Cylinder Assembly
Before assembly, clean all parts including the master
cylinder with brake fluid or alcohol.
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 diffi-
cult to wash off completely, and will eventually de-
teriorate the rubber used in the disc brake.
Apply brake fluid to the new parts and to the inner wall of

Using compressed air, remove the pistons. One way to
remove the pistons is as follows.
Install a rubber gasket [A] and a wooden board [B] more
than 10 mm (0.39 in.) thick on the caliper half, and fas-
ten them together with a suitable bolt and nut as shown.
Leave one of the oil passages [C] open.
Lightly apply compressed air [D] to the oil passage until
the pistons hit the rubber gasket. Block the hose joint
opening [E] during this operation if the caliper half has
