REMOVAL & INSTALLATION
See Figures 1, 2, 3 and 4
- Raise and safely support the vehicle.
- Remove the wheel and tire assembly.
- Remove the brake hose from the caliper assembly.
- Remove the retaining clip from the parking brake cable at the caliper. Disengage the parking brake cable end from the lever arm.
- Depending on vehicle application, hold one of the slider pin hex-heads with an open-end wrench, then remove the pinch bolt or pin retainer. Repeat for the other slider pin. Lift the caliper assembly away from the anchor plate. Remove the locating/slider pins and boots from the anchor plate/support bracket.
- Apply Silicone Dielectric Compound or equivalent to the inside of the locating/slider pin boots and to the pins.
- Position the slider pins and boots in the anchor plate. Position the caliper assembly on the anchor plate. Make sure the brake pads are installed correctly.
- Remove the residue from the pinch bolt threads, then apply one drop of Threadlock and Sealer E0AZ-19554-AA or equivalent. Install the pinch bolts or pin retainers, then tighten to 23-26 ft. lbs. (31-35 Nm) while holding the slider pins with an open-end wrench.
- Attach the cable end to the parking brake lever. Install the cable retaining clip on the caliper assembly.
- Using new washers, connect the brake flex hose to the caliper. For vehicles through 1992, tighten the retaining bolt to 8-11 ft. lbs. (11-16 Nm). For 1993-95 vehicles, tighten the retaining bolt to 30-40 ft. lbs. (41-54 Nm).
- Bleed the brake system, filling the master cylinder as required.
- Install the wheel and tire assembly, then lower the vehicle. Pump the brake pedal prior to moving the vehicle to position the brake pads.
See Figure 5
- Remove the caliper assembly from the vehicle following the procedure earlier in this section.
- Mount the caliper in a vise with soft-jawed protectors.
- Using Rear Caliper Piston Adjuster T87P-2588-A or equivalent, turn the piston and adjuster counterclockwise to remove the piston from the bore.
- Using snapring pliers, remove the snapring retaining the pushrod from the caliper.
The snapring and spring cover are under tension caused by spring load. Be careful when removing the snapring to avoid injury.
- Remove the spring cover, spring, washer and key plate, then pull out the pushrod strut pin from the piston bore.
- Remove the parking brake lever return spring, then unscrew the parking brake lever stop bolt and pull the parking brake lever out of the caliper housing.
- Clean all metal parts with isopropyl alcohol. Use clean, dry compressed air to clean the grooves and passages. Inspect the caliper bores for damage or excessive wear. If the piston is pitted, scratched or scored replace the piston.
- Lightly grease the parking brake lever bore and the lever shaft seal with Silicone Dielectric Compound or equivalent. Press the parking brake lever shaft seal into the caliper bore.
- Grease the parking brake shaft recess and lightly grease the parking brake lever shaft. Install the shaft into the caliper housing.
- Install the lever stop bolt into the caliper housing and tighten the bolt to 4.5-7.0 ft. lbs. (6-9 Nm).
- Attach the parking brake lever return spring to the stop bolt, then install the free end into the parking brake lever slot.
- Install a new O-ring seal in the groove of the pushrod. Grease the pushrod end with Silicone Dielectric Compound or equivalent.
- Position the strut pin in the caliper housing and in the recess of the parking brake lever shaft. Install the pushrod into the bore. Make sure the pin is positioned correctly between the shaft recess. Install the flat washer, pushrod, spring and spring cover, in that order.
