    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. Before servicing the vehicle, refer to the Precautions Section.
    2.  
    3. Remove 2 / 3 of the brake fluid from the master cylinder assembly.
    4.  
    5. Remove the tire and wheel assembly. Mark a relationship between the wheel and the wheel stud for re-installation purposes.
    6.  
    7. Install 2 wheel nuts to retain the rotor.
    8.  
    9. Remove the brake hose from the caliper and discard the copper washers.
    10.  
    11. Plug the openings in the caliper and the brake hose to prevent brake fluid loss and contamination.
    12.  
    13. Remove the two caliper mounting bolts.
    14.  
    15. Remove the caliper body assembly from the vehicle. Pivot the caliper assembly up to clear the rotor and then slide it inboard off the pin sleeve.

    To install:

    1. Inspect the caliper bolt boots, pins and sleeve bolt for cuts, tears or deterioration. Replace as necessary.
    2.  
    3. Lubricate the mounting surfaces and the mounting sleeves.
    4.  
    5. Hold the caliper body assembly in the position from which it was removed, and start it over the end of the pin sleeve.
    6.  
    7. As the caliper body assembly approaches the pin boot, work the large end of the pin boot in the caliper body groove. Push the caliper body fully onto the pin.
    8.  
    9. Pivot the caliper body assembly down, using care not to damage the piston boot on the inboard shoe. Compress the sleeve boot by hand as the caliper body moves into position to prevent boot damage.
    10.  
    11. After installing the caliper assembly into position, recheck the installation of the pad clips. If necessary, use a small prying tool to reset or center the pad clips.
    12.  
    13. Torque caliper mounting bolts to 32 ft. lbs. (43 Nm)
    14.  
    15. Connect the brake hose to the brake caliper and torque the bolt to 40 ft. lbs. (54 Nm).
