  1. Apply and fully release the parking brake 6 times.
  2. Verify that the parking brake pedal releases completely:
    • Turn the ignition on. Verify that the Red brake indicator lamp is off.
    • If the Red brake indicator lamp is on, ensure the parking brake pedal is in release mode and fully returned to stop. Remove the slack in the front parking brake cable by pulling downward on the cable.
  3. Raise support the vehicle. Remove the rear wheels and tires.
  4. Remove both rear caliper brackets. See CALIPER BRACKET (REAR)  under REMOVAL & INSTALLATION.
  5. Relieve tension on the park brake system at the park brake equalizer. Remove both rear brake rotors. See BRAKE ROTOR (REAR)  under REMOVAL & INSTALLATION.
  6. Set the Drum-to-Brake Shoe Clearance Gauge (J-21177-A) inside of the park brake drum at the widest point. Place the contacts on the tool to the widest point of the drum. Tighten the set screw on the tool to ensure the proper measurement when removing the tool from the drum.
  7. Position the Drum-to-Brake Shoe Clearance Gauge over the park brake shoe at the widest point. Turn the adjuster on the actuator until the park brake shoe just contacts the Drum-to-Brake Shoe Clearance Gauge.
  8. Repeat steps six and seven for the opposite side.
  9. Install both rear brake rotors. See BRAKE ROTOR (REAR)  under REMOVAL & INSTALLATION.
  10. Install both rear caliper brackets. See CALIPER BRACKET (REAR)  under REMOVAL & INSTALLATION.
  11. Install the rear wheels and tires. Adjust the parking brake by turning the nut at the equalizer (2) while spinning both rear wheels. See Fig 1 . When either rear wheel starts to drag, back off the nut one full turn.
  12. Lower the vehicle to curb height. Apply the parking brake, then inspect for rotation of the rear wheels. If the rear wheels rotate during this inspection, readjust the parking brake shoes. See DISC BRAKE PARK BRAKE ADJUSTMENT  .
  13. Release the parking brake. Verify that the wheels rotate freely. Lower the vehicle.
