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 the caliper.
  2.  
  3. Suspend the caliper with a piece of wire.
    WARNING
    Do not allow calipers to hang from the flexible hoses; doing so can damage the hoses.

  4.  
  5. Remove the inboard lining and the outboard lining.
  6.  
  7. Use a wire brush to remove any corrosion from the machined surfaces of the steering knuckle and the caliper.
  8.  

To install:

  1. Lubricate the caliper and the steering knuckle, or support, sliding surfaces and the spring with Aeroshell® No.5 or the equivalent.
  2.  
  3. Place the new pad in a vise.
  4.  
  5. Compress the brake pad tangs as necessary to obtain a secure fit between the outer brake pad and the caliper.
  6.  
  7. Install the outer brake pad onto the caliper. Use a C-clamp to install the pad onto the caliper if it is necessary. Do not allow the C-clamp to come in contact with the lining. Insert a used brake pad between the C-clamp and the new brake lining.
  8.  
  9. File the leading edge of the brake pad tang to aid in the installation of the brake pad to the caliper.
  10.  
  11. Install the caliper.
    CAUTION
    Pump the brakes until the brake pedal is firm before moving the vehicle. Check the brake fluid level in the master cylinder after pumping the brakes.
