Disc Brake Caliper: Disassembly

  1. Raise and support vehicle. Remove tire and wheel assembly.
  2. Remove the caliper from the vehicle. See DISC BRAKE CALIPERS  under REMOVAL & INSTALLATION.
    3. CAUTION: Do not place your fingers in front of the piston in order to catch or protect the piston while applying compressed air. This could result in serious injury.
  3. Use just enough air pressure to ease the piston out of the bore. You can damage a blow-out piston even with the padding. Insert a block of hard wood or a shop cloth into the caliper interior to catch the piston as it is forced out of the bore with compressed air.
  4. Remove the piston from the caliper by applying compressed air to the caliper brake hose connector hole.
  5. Remove the rubber boot from the caliper groove.
  6. Use a flat plastic tool in order to remove the piston seal from the caliper groove.
  7. Remove the bleeder valve from the caliper.
  8. Clean the following items in brake fluid:
    • The Caliper Set Ring
    • The Piston
    • The Caliper Cylinder Bore
  9. Inspect the piston for scoring, corrosion and any damage to the chrome plating. Replace the piston if any of these conditions exist.
  10. Inspect the caliper cylinder bore for scoring, pitting and corrosion. Use a crocus cloth to polish out any light corrosion. If the corrosion cannot be removed, replace the caliper.
