Pad thickness may be checked by removing the wheel and looking through the inspection port in the caliper assembly.

Replace the disc brake pads when the pad thickness is at the following minimum thicknesses:



Navajo and 1994 B Series Pick-up: 0.12 inch (3.0mm)

CAUTION
Older brake pads or shoes may 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.

  1. To avoid fluid overflow when the caliper piston is pressed into the caliper cylinder bores, remove or siphon part of the brake fluid out of the master cylinder reservoir (connected to the front disc brakes). Discard the removed fluid.
  2.  
  3. Loosen the wheel lug nuts.
  4.  
  5. Raise and safely support the front of the vehicle. Remove the wheel.
  6.  
  7. Place an 8 in. (203mm) C-clamp on the caliper and tighten the clamp to bottom the caliper pistons in their bores. Remove the clamp.
  8.  
  9. Remove the two caliper slide pin bolts and lift the caliper from the anchor plate.
  10.  

Use care to retain as much of the original caliper slide pin grease as possible.

  1. Position the caliper on a frame member or suspend it with some wire. Do not allow the caliper to hang by the brake hose.
  2.  
  3. Remove the brake pads and, if necessary, the anti-rattle clips from the anchor plate.
  4.  
  5. Remove the shims, if any, from the brake pads for re-use.
  6.  

To install:

  1. If removed, install the anti-rattle clips.
  2.  
  3. Install the brake pads to the anchor plate.
  4.  
  5. Position the caliper over the brake pads and align the slide pin mounting holes.
  6.  
  7. Install the slide pin bolts and tighten them to 21-26 ft. lbs. (28-36 Nm).
  8.  
  9. Install the wheel and snug the lug nuts.
  10.  
  11. Lower the vehicle and tighten the lug nuts to 100 ft. lbs. (135 Nm).
  12.  

The first couple of times you apply the brakes, the pedal may go to the floor. Continue to pump the brake pedal until it feels firm.

  1. Start the engine and apply the brakes several times to readjust the caliper pistons. Ensure that the pedal feels firm before operating the vehicle.
