  1. Remove the disc brake pads as previously described.
  2.  
  3. Disconnect the brake hose from the caliper. The fixed caliper is mounted by two bolts, cut the safety wire and remove the bolts. Remove the caliper. The sliding caliper support is held on by two mounting bolts, cut the safety wire and remove the bolts. Remove the caliper support.
  4.  
  5. Installation is the reverse of removal. Be sure to safety wire the mounting bolts.

  1. Remove the caliper as previously described.
  2.  


WARNING
The caliper halves must not be separated. If brake fluid leaks from the bridge seal, replace the caliper assembly.

  1. Clean the caliper assembly of all accumulated mud and dust.
  2.  
  3. Remove the retaining rings. Remove the dust covers.
  4.  
  5. Hold one piston with a finger so that it will not come out and gradually apply air pressure to the brake line fitting. This should cause the other piston to come out, but if the piston you are holding begins moving before the other, switch your finger over and remove the more movable one first.
  6.  
  7. Carefully remove the other piston.
  8.  
  9. With a finger, carefully remove both piston seals.
  10.  
  11. Thoroughly clean all parts in brake fluid.
  12.  
  13. Inspect, as follows:
  14.  
    1. Check cylinder walls for damage or excessive wear. Light rust, etc. should be removed with fine emery paper. If the wall is heavily rusted, replace the caliper assembly.
    2.  
    3. Inspect the pad, as previously described.
    4.  
    5. Inspect the piston for uneven wear, damage or any rust. Replace the piston if there is any rust, as it is chrome plated and cannot be cleaned.
    6.  
    7. Replace piston seals and dust covers.
    8.  

  15. Coat the piston seal with brake fluid and carefully install the piston seal.
  16.  
  17. Install the dust seal onto the piston. Coat the piston with brake fluid. Install the piston and seal assembly and install the retaining ring.
  18.  
  19. Repeat Steps 9 and 10 for the other piston.
  20.  
  21. Install the caliper assembly. Fill the master cylinder and bleed the system.
  22.

  1. Remove the caliper cylinder from the car. (See the appropriate preceding Brake Pad Removal procedure).
  2.  
  3. Carefully remove the dust boot from around the cylinder bore.
  4.  
  5. Place a folded towel between the piston and housing. Apply compressed air to the brake line union to force the piston out of its bore. Be careful, the piston may come out forcefully.
  6.  
  7. Remove the seal from the piston. Check the piston and cylinder bore for wear and/or corrosion. Replace components as necessary.
  8.  

To assemble:
  1. Coat all components with clean brake fluid.
  2.  
  3. Install the seal and piston in the cylinder bore, after coating them with the rubber lubricant supplied in the rebuilding kit. Seat the piston in the bore.
  4.  
  5. Fit the boot into the groove in the cylinder bore.
  6.  
  7. Install the caliper cylinder assembly on to the support.
  8.  
  9. Fill the master cylinder and bleed the system.
  10.
