5. Using a soft tool such as a plastic trim stick (1),
work the piston seal (2) out of its groove in caliper
piston bore. Discard the used seal.
6. Clean the piston bore and drilled passage ways
with alcohol or a suitable solvent. Wipe it dry using
only a lint-free cloth.
Inspection
1. Inspect both the piston and bore for scoring or pitting. Bores that show light scratches or corrosion can usually
be cleared of the light scratches or corrosion using crocus cloth.
2. Remove deposits on the piston using a soft brass wire brush or a rough shop towel. Do not clean piston with a
polishing or emery cloth because this will damage the chrome-plated surface. Replace the piston if the chrome
plated surface is damaged. If the piston is jammed or if the cylinder bores are scored or rusted, replace the
complete brake caliper. Remove small, light rust spots in the cylinder bore with a polishing cloth. Remove heavy
rust spots in front of the groove for the piston seal using fine-grit emery paper (grit size 380 to 500).
3. Inspect the caliper guide sleeves for smooth oper-
ation. Repair and grease caliper sleeves as
necessary.
