CLEANING AND INSPECTION
The boot, piston seal, rubber bushings and sleeves are
to be replaced each time the caliper is overhauled.
Discard -- do not bother to clean and inspect
--
these
parts.
Clean all other parts in alcohol or brake fluid. Use dry,
filtered compressed air to dry parts and blow out all
passages in the caliper and bleeder valve.
CAUTION: The use of lubricated shop air will leave
a
Elm of mineral oil on the metal parts. This may damage
rubber parts when they come in contact after reassembly.
1.
Check the mounting bolts for corrosion, breaks in
the plating or other damage. Do not use abrasives in
an attempt to clean the bolts

2. Carefully examine outside of piston for scoring,
nicks, corrosion and worn or damaged chrome plating.
If any surface defects are detected, replace the piston.
*
CAUTION: The piston OD is the primary sealing
surface in the caliper assembly. It is manufactured and
plated to close tolerances. It cannot be refinished or
repaired in the field.
3. Check the bore in the caliper for major defects with
the exception of plating damage. The piston bore is
not plated and stains or minor corrosion can be
polished with abrasive cloth. Thoroughly clean the
caliper after the use of any abrasive. If the bore cannot
be cleaned up in this manner, replace the caliper.
