CaliperFluid Seal Damage
The fluid seals [A]
around the piston maintain the proper
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  as
well. Also, replace all seals every other time the pads are
Caliper Dust Seal/Friction Boot Damage
Check that the dust seals  and friction boot  are not
cracked, worn, swollen, or otherwise damaged.
*If they show any damage, remove the caliper bracket and

Caliper Holder Shaft
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-
