2000 GMC Sierra Truck Change Rear Emergency Brake Shoes

GMC trucks, like most other modern automobiles, come with a hand brake that helps lock the vehicle into place. Although termed an "emergency brake," using it while also applying the foot brakes increases the likelihood of losing control. That's why it's more accurately called the parking or hand brake. Ideally, the emergency brake is used only when the truck is parked, and even then only when it is parked on an incline. Avoiding overuse can extend the life of the brake shoes. When they do wear out, you can replace them in a few hours.

Tools Used[edit]

2 wheel blocks
Floor jack
2 jack stands
Ratchet with socket set
Lug wrench
Brake cleaner
Drip pan
Replacement brake shoes
Safety goggles (optional)

Change Rear Emergency Brake Shoes[edit]

  • Install wheel blocks over the front two wheels to keep them from moving while changing the brake shoes.
  • Lift the rear end of the truck using the floor jack. Place the jack stands underneath a solid area of the frame and lower the truck onto the stands. Remove the jack once the weight is placed solidly on the stands.
  • Loosen the lug nuts on the rear wheel using the lug wrench. It's best to finish changing one brake pad before removing the second wheel. Pull the wheel off by hand once each of the lug nuts has been removed. Put the wheel and lug nuts in a safe location.
  • Place the drip pan beneath the brake assembly and thoroughly spray the assembly with the brake cleaner. Be sure to cover or hide your eyes from the brake cleaner as any mist can lead to severe irritation. Use goggles if necessary.
  • Remove the brake caliper bolts using the ratchet and correct socket. Be cautious of the brake line. Lift the caliper off the rotor and let it hang without pulling on the line. Again, place the caliper bolt in a safe place, but away from the other pieces.
  • Locate and remove the parking brake retainer clip.
  • Remove the cable from the brake by pulling it forward, then disconnect the cable from the emergency brake lever.
  • Spread the shoes apart and remove the adjuster screws and springs from both of the brake shoes.
  • Remove the emergency brake shoes. Keep the spring and level in place for now. Spray the brake area with brake cleaner.
  • Take apart the brake shoe assembly. Pay attention to the location of the different parts as these will illustrate how to assemble the new brake shoes.
  • Reinstall the assembly onto the plate with the screws and pins on the new brake shoes. Install the adjuster screw and spring. Make sure the new shoes don't touch the rotor unless needed, and that the lever cable and brake line connections are intact.
  • Reinstall the brake caliper bolts and tighten them into place.
  • Place the wheel back onto the rotor and tighten all of the lug nuts until the wheel is secure.
  • Repeat step 3 through 13 on the other wheel.
  • Lift the truck off the stands using the floor jack. Remove the stands and lower the truck to the ground. Test the emergency brake by pulling on the lever in the cabin.
