  Q: How to replace the brake shoes on GMC Envoy?

  A: In order to replace the brake shoes, obtain the required tools: j 38400 (Brake Shoe spanner & spring remover), and j 21177 - a (Drum to Brake Shoe clearance gage). Start with lifting and taking off the rear Brake Drum assembly. Clean the rear brake shoes with denatured alcohol and make the brake shoes lowest to decrease the tension on the retractor spring while removing the adjuster assembly. The retake the retractor spring from the secondary Brake Shoe and then the second Brake Shoe from the backing plate using a pair of channel locks. Repeat this process for the primary Brake Shoe, but be sure to take out also the return spring. Then press the lock-tab for the park brake cable using pocket flat-blade screwdriver, while holding it simultaneously, push the park brake cable forwards in order to unlock it from the retainer and take out of the lever but remembering not to separate the return spring from the lever. For installation, lubricate the surface of contact between the rear brake shoes and the backing plate using a small quantity of high-temperature silicone grease, install the park brake cable in the lever and feel a snap or clip when seated. Mount the retractor spring to the backing plate, then the primary Brake Shoe with the assistance of channel locks, then the secondary Brake Shoe. The retractor spring can be manually installed in either (J 38400 ) or channel locks. Then install the park brake adjusting hardware and adjust the rear brake shoes using the j22364-01 before reinstalling the rear Brake Drum and bringing the vehicle down.
