6. Remove caliper piston seal with wood or plastic tool (Fig. 21). Do not use metal tools as they will scratch piston bore.
7. Remove caliper mounting bolt bushings and boots (Fig. 22).
CLEANING
Clean the caliper components with clean brake fluid or brake clean only. Wipe the caliper and piston dry with lint free towels or use low pressure
compressed air.
CAUTION: Do not use gasoline, kerosene, thinner, or similar solvents. These products may leave a residue that could damage the piston and seal.
INSPECTION
The piston is made from a phenolic resin (plastic material) and should be smooth and clean.
The piston must be replaced if cracked or scored. Do not attempt to restore a scored piston surface by sanding or polishing.
CAUTION: If the caliper piston is replaced, install the same type of piston in the caliper. Never interchange phenolic resin and steel caliper pistons.
The pistons, seals, seal grooves, caliper bore and piston tolerances are different.
