BRAKES 12-15
Calipers
•
Apply brake fluid to the outside of the pistons [A], and
push them into the cylinder by hand. Take care that nei-
ther the cylinder nor the piston skirt gets scratched.
•
Replace the rubber boots [B] if they are damaged.
•
Apply a thin coat of silicone grease to the caliper holder
shafts [C] [D] (Silicone grease is a special high tempera-
ture, water-resistant grease).

Front Brake Caliper Piston and Cylinder Damage
Inspection
•
Visually inspect the piston [A] and cylinder surfaces [B].
Replace the caliper if the cylinder and piston are badly
scored or rusty.
Front Brake Caliper Holder Shaft Wear Inspection
The caliper body must slide smoothly on the caliper holder
shafts [A]. If the body does not slide smoothly, one pad will
wear more than the other, pad wear will increase, and con-
stant drag on the disc will raise brake and brake fluid tem-
perature.
•
Check to see that the caliper holder shafts are not badly
worn or stepped, and that the rubber boots [B] are not
damaged.
If the rubber boot is damaged, replace the rubber boot.
If caliper holder shaft is damaged, replace the caliper
ho
lder shaft and rubber boot as a unit.
