- Remove the brake caliper. Blow compressed air into the brake caliper hole in order to remove the brake caliper piston. The piston will come out through the piston boot. Inspect and replace the brake caliper piston if any of the following conditions are found: Scoring, nicks, corrosion or worn or damaged chrome plating. Remove the dust boot retaining ring. See Figure .
- Use a flat-bladed tool in order to remove the brake caliper piston boot. Do not scratch the housing bore. Use a small wooden or plastic tool in order to remove the piston seal from the groove in the caliper bore. Inspect the caliper bore and the seal grooves for the following conditions:
- Scoring
- Nicks
- Corrosion
- Wear
- Use a piece of crocus cloth in order to polish out light corrosion. Replace the caliper housing if corrosion in and around the seal groove cannot be cleaned with a piece of crocus cloth. Inspect the seal groove in the caliper bore for nicks or burrs. Replace the caliper if the seal groove is damaged. Inspect and replace any brake caliper bolt pin boots that exhibit any of the following conditions:
- Cuts
- Tears
- Deterioration (Inspect the brake caliper bolts for corrosion or damage.)
- Replace any corroded brake caliper bolts. Remove the bleeder valve cap and the bleeder valve from the brake caliper housing. See Figure . Clean all the parts with clean, denatured alcohol. Dry all the parts with filtered, non-lubricated compressed air. Use filtered, non-lubricated compressed air in order to blow out all of the passages in the caliper housing and the bleeder valve.
