Install the anti-rattle spring [A] in the caliper body as
Install the piston insulator.
Install the pads.
Wipe up any spilled brake fluid on the caliper with wet
Fluid Seal Damage Inspection
The fluid seal around the piston maintains the proper
pad/disc clearance. If this seal is not satisfactory, pad wear
will increase, and constant pad drag on the disc will raise
brake and brake fluid temperature.
Replace the fluid seal under any of the following condi-
Fluid leakage around the pad.
There is a large difference in left and right pad wear.
The seal is stuck to the piston.
If the fluid seal is replaced, replace the dust seal as well.
Dust Seal and Cover Damage Inspection
Check that the dust seal and covers are not cracked,
worn, swollen, or otherwise damaged.
If they show any damage, replace them.
Piston Cylinder Damage Inspection
Visually inspect the piston and cylinder surfaces.
Replace the cylinder and piston if they are badly scored
Caliper Holder Shaft Wear Inspection
The caliper body must slide smoothly on the caliper holder
shafts. 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-
Check to see if the caliper holder shafts are not badly worn
or stepped, or rubber friction boot are not damaged.
If the shafts and rubber friction boot are damaged, replace
the rubber friction boot and the caliper holder.
