Ford Mustang/Capri 1979-1988 Repair Guide

Brake Pads



See Figures 1 and 2

When installing new brake linings, replace the pads at both rear wheels to avoid uneven braking.

  1. Raise the vehicle and install safety stands. Block both front wheels if a jack is used.
  3. Remove the rear wheel covers.
  5. Remove the wheel and tire assemblies from the axle. Use care to avoid damage or interference with the splash shield.

If you are not thoroughly familiar with the procedures involved in brake service, only disassemble and assemble one side at a time, leaving the other brake assembly intact as a reference.

  1. Remove the caliper as outlined below. It is not necessary to disconnect the brake line. Simply wire the caliper to the frame to prevent the brake line from stretching or breaking.
  3. Remove the pads and inspect them. If they are worn to within 1 / 8 in. (3mm) of the shoe surface, they must be replaced. Do not replace pads on just one side of the car, since uneven braking will result.

Brake shoes contain asbestos, which has been determined to be a cancer causing agent. Never clean the brake surfaces with compressed air! Avoid inhaling any dust from any brake surface! When cleaning brake surfaces, use a commercially available brake cleaning fluid.

To install:
  1. Remove the disc and install the caliper without the pads.
  3. Adjust the piston depth, using Brake Piston Turning Tool T75P-2588-B or equivalent, as follows:
    1. Seat the turning tool firmly against the piston by holding the shaft and rotating the handle.
    3. Loosen the handle 1 / 4 turn. Hold the handle and rotate the tool shaft clockwise until the caliper piston bottoms in its bore. The piston will continue to turn after it bottoms.
    5. Rotate the handle until the piston is firmly seated, then remove the tool.

  5. Remove the caliper from the anchor plate.
  7. Lubricate the anchor plate sliding ways with Disc Brake Caliper Grease D7AZ-019590-A or equivalent.

Use only the specified grease, since a lower temperature type of lubricant may melt and contaminate the brake pads. Do not permit any lubricant to get on the braking surface!

  1. Install the anti-rattle clip on the lower rail of the anchor plate.
  3. Place the inner brake shoe and lining assembly on the anchor plate with the lining toward the rotor.
  5. Install the disc and retainer nuts.
  7. Place the outer brake shoe and lining assembly on the anchor plate with the lining toward the rotor, and the wear indicator toward the top.
  9. Reinstall the caliper, as outlined below.
  11. Repeat Steps 4-14 for the other side of the vehicle.
  13. Install the wheel and tire assemblies and tighten the wheel lug nuts. Install the wheel covers.
  15. Remove the safety stands and lower the vehicle. Unblock the front wheels, if applicable.
  17. Check the level of the brake fluid, and add new fluid if necessary.
  19. Be sure a firm brake pedal application is obtained, and then road test for proper brake operation, including parking brakes.
