Removal & Installation




CAUTION
Dust and dirt accumulating on brake parts during normal use may contain asbestos fibers from production or aftermarket brake linings. Breathing excessive concentrations of asbestos fibers can cause serious bodily harm. Exercise care when servicing brake parts. Do not sand or grind brake lining unless equipment used is designed to contain the dust residue. Do not clean brake parts with compressed air or by dry brushing. Cleaning should be done by dampening the brake components with a fine mist of water, then wiping the brake components clean with a dampened cloth. Dispose of cloth and all residue containing asbestos fibers in an impermeable container with the appropriate label. Follow practices prescribed by the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA) for the handling, processing, and disposing of dust or debris that may contain asbestos fibers.

  1. Remove 2 / 3 of the brake fluid from the master cylinder assembly.
  2.  
  3. Remove the tire and wheel assembly. Mark a relationship between the wheel and the wheel stud for re-installation purposes.
  4.  
  5. Install 2 wheel nuts to retain the rotor on the vehicle.
  6.  
  7. Install a large C-clamp over top of the caliper housing and against the back of the outboard shoe. Slowly tighten the C-clamp until the piston(s) are pushed into the caliper bore.
  8.  
  9. Disconnect the bolt attaching the brake hose fitting to the brake caliper.
  10.  
  11. Plug the opening in the caliper housing and brake line to prevent brake fluid loss and contamination.
  12.  
  13. Remove the caliper mounting bolts.
  14.  
  15. Remove the brake caliper housing from the rotor and mounting bracket.
  16.  
  17. If the caliper is to be replaced or repaired remove the brake pads from the caliper or mounting bracket.
  18.  

To install:

  1. Fully inspect the brake caliper bushing assemblies for cuts, tears or deterioration and replace parts as needed.
  2.  
  3. Inspect the slide bolts for corrosion. If corrosion is found, replace the slide bolts and bushings before installing the brake caliper assembly.
  4.  
  5. Before installing the caliper, make sure the piston(s) are seated in the bore, and that the brake pads are correctly installed.

  10.  
  11. Install the caliper bolts and torque the bolts to 70 ft. lbs. (95 Nm).
  12.  
  13. Install the brake hose inlet fitting to the caliper and torque the bolt to 24 ft. lbs. (32 Nm).
  14.  
  15. Remove wheel nuts securing the brake rotor to the hub.
  16.  
  17. Install the tire and wheel assembly.
  18.  
  19. Fill the master cylinder to the proper level.
  20.
