Brake Pads


Removal & Installation

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.
  3. Remove or disconnect the following:
    Prevent strain or other damage to the brake hose by supporting the caliper assembly with a strong piece of wire hanging from the strut.

    Some of the fluid from the master cylinder
    2 caliper guide pin bolts
    Caliper assembly by swinging the top part of the caliper away from the brake rotor edge, then lift the caliper assembly up

    Outboard brake pad by prying the brake pad retaining clip over raised area on the caliper. Then slide the pad down and off the caliper.

  5. Before removing the inboard brake pad, use a large C-clamp to press the piston back into the caliper. This will prevent possible damage to the caliper piston. It is good practice to remove some ( 1 / 3 - 1 / 2 ) of the brake fluid from the reservoir. This is because as the caliper piston is pushed back into the caliper, brake fluid will be pushed back through the lines, back into the master cylinder and fluid reservoir, possibly causing the reservoir to overflow.

    Inboard brake pad by pulling away from piston until the retainer clip is free from the cavity in the piston.

    Fig. Removal and installation of the disc brake pads



To install:

  1. Lubricate both the caliper mating surface and the machined abutment surfaces with multi-purpose lubricant.
  3. Before brake pad installation, be sure to lightly coat the outer backing plate surface of the new brake pads with a disc brake pad anti-squeal lubricant, usually a gel-like material that deadens any high-frequency vibration that can be the source of disc brake squeal.
  5. Install or connect the following:

    Brake pads into the caliper assembly making sure both pads are seated securely onto the caliper
    Caliper assembly back into position over the brake rotor
    Caliper guide pin bolts and torque to 17 ft. lbs. (23 Nm)
    Wheels and lug nuts. Torque the lug nuts, in a star pattern sequence, to 100 ft. lbs. (135 Nm).

  7. Top off the master cylinder to the appropriate level, using DOT 3 type brake fluid only.
  9. Before moving the vehicle, pump the brakes until a firm pedal is obtained. Road test the vehicle to make sure the brake operation is normal.
