  Q: How to Properly Service a Parking Brake Shoe on GMC Envoy?

  A: The process of replacing the park Brake Shoe begins by releasing the brake then lifting the vehicle. Switch off the park brake while raising the vehicle for work on the brakes. Remove the tire and wheel first. Then detach the brake caliper along with bracket but keep them together. Support and position them to one side. The first step involves rotor removal together with disconnection of the park brake cable from the park brake lever. The park Brake Shoe requires you to move it downward until it breaks free from the hold down spring before elevating and removing it away from the back plate to slide off from the actuation mechanism. Clean park brake components at the axle flange with a clean towel after pulling out the shoe over the flange. Set the adjustment screw at full home position within the notched adjustment nut before rotating it 1/4 turn. Ensure that both the screw slot and tappet slot remain aligned with the backing plate surface. Detergent alcohol cleans the rear backing plate before its drying happens through ungreased filtered air supply. The installation of new park brake shoes begins with placing one over the axle flange followed by positioning it onto the actuation mechanism. Pass the lower shoe end past the hold down spring towards the backing plate before resting it at the backing plate position. Push the shoe by its upper section beneath the hold down spring and confirm the shoe sits in the central position on the backing plate between the actuation mechanism slots. Operation of the park brake system must be tested by hand through observation of the actuation mechanism after moving the actuator lever. Restore the park brake cable to its connection point on the park brake lever while modifying the park Brake Shoe position. After that, add back the brake rotor followed by the brake caliper and mounting bracket. Lower the vehicle and then complete installation of the tire with its wheel.
