CaliperFluid Seal Damage
The fluid seals [A]
around the piston maintain the proper
pad/disc clearance.
If the seals are not satisfactory, pad
wear will increase, and constant pad drag on the disc will
raise brake and brake fluid temperature.
.
Replace the fluid seals under any of the following condi-
tions; (a) fluid leakage around the pad; (b) brakes over-
heat (c) there is a large difference in inner and outer pad
wear; (d) the seal is stuck to the piston.
* If the fluid seal is replaced, replace the dust seal [8] as
well. Also, replace all seals every other time the pads are
changed.
Caliper Dust Seal/Friction Boot Damage
.
Check that the dust seals [8] and friction boot [0] are not
cracked, worn, swollen, or otherwise damaged.
*If they show any damage, remove the caliper bracket and
replace them.

Caliper Piston and Cylinder Damage
.
Visually inspect the piston [E] and cylinder surfaces.
*Replace
the caliper if the cylinder and piston are badly
scores or rusty.
Caliper Holder Shaft
Wear
The caliper body must slide smoothly on the caliperholder
shaft [F]. 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 shaft are not badly
worn or stepped, and that the rubber friction boots are
not damaged.
*If the rubber friction boot is damaged, replace the rubber
frictionboot. Toreplacethefrictionboot,
remove the pads
and the caliper bracket.
* If the caliper holder shaft is damage, replace the caliper
bracket.
