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.


NOTE
There are 2 caliper designs and they can be identified by the method used to secure the assembly to the spindle bracket. The Delco caliper is secured by a bolt and sleeve combination. The Bendix caliper assembly is secured by a slider, spring and bolt.

  1. Remove the cover on the master cylinder and siphon enough fluid out of the reservoirs to bring the level to 1 / 3 full. This step prevents spilling fluid when the piston is pushed back.
  2.  
  3. Raise and support the vehicle safely. Remove the front wheels and tires.
  4.  
  5. Position a C-clamp around the outside pad and caliper; tighten the C-clamp until the caliper piston bottoms in its bore.

  7. Remove the brake hose from the caliper by removing the inlet fitting.
  8.  
  9. Remove the bolt and sleeve or bolt and slider assemblies that hold the caliper and then lift the caliper off the rotor.
  10.  
  11. Remove the inboard and outboard pad.

To install:

  1. Install the pads onto the caliper.
  2.  
  3. Position the caliper onto the knuckle/rotor assembly and secure the assembly with the mounting bolts or sliders.
  4.  
  5. Reconnect the brake line to the caliper.
  6.  
  7. Bleed the brakes
  8.  
  9. Pump the brake pedal and verify there is minimal brake pedal travel.
  10.  
  11. Check the brake fluid level. Install the tire and wheel assembly.
