5.5.3.2 Assembly of master cylinder
Before assembly, clean all parts with brake fluid or
alcohol, including master cylinder.
Notes
Except brake pad and disc brake, other brake
parts can only be cleaned with disc brake fluid,
isopropyl alcohol or ethanol. Dot not clean the
above parts with other liquid. Gasoline, oil or
other gasoline distillates may corrode rubber parts.
If oil spills onto any part, it will be difficult to clean
thoroughly and eventually corrode the rubber
parts inside the disc brake.
●Apply brake fluid to new parts and inner wall of brake
cylinder.
●Be careful not to scratch the piston or the inner wall of
brake cylinder.
●Install plunger assembly. If the front reservoir or rear
reservoir on the plunger assembly is damaged, replace it
with a new one.
Incorrect use or reverse installation of front and rear
reservoirs should be avoided.
●Press the plunger assembly down and install it into the
plunger spring using a special tool—inside circlip pliers,
and press it into the dust cap.
●Apply silicon grease to the pivot bolt of brake lever.
●Install the lever, and tighten the lever bolt and locknut.
