How to Replace Drum Brake Shoes

Virtually all vehicles manufactured up to the mid-1970s used drum brakes on all four wheels. However, most modern vehicles use disc brakes on the front of the vehicle and drum brakes on the rear only. Drum brakes operate when the internal brake shoes press out against a drum that rotates with the wheel. The brake shoes on your drum brakes will eventually wear out and will need to be replaced.

Instructions

1

Raise the rear of the vehicle with a hydraulic jack. Place jack stands under each side of the rear axle. Lower the hydraulic jack so that the rear of the vehicle is supported by the jack stands.

2

Remove the lug nuts from the rear wheels with a lug wrench turned in a counterclockwise direction. Remove the rear wheels from the vehicle and set them aside. Slide the brake drums off of the rear wheel hubs and set them aside.

3

Work on one side of the vehicle at a time. Locate both brake shoes on the right and left side of the wheel hub. Locate the brake shoe return spring which connects the two brake shoes at the top of the wheel hub. Remove the brake shoe return spring by placing a pair of brake spring pliers over the end of the spring. Pull on the pliers to stretch the spring until it can be unhooked from the brake shoes. Remove the spring and set it aside.

4

Place a brake shoe removal tool over the circular brake shoe retainer clip, located at the center of each brake shoe. Push down on the tool and rotate it counterclockwise. Remove the tool, the retainer clip, and the spring behind the clip and set them aside. Repeat this step for both brake shoes.

5

Pull the brake shoes from the wheel hub and discard them. Place new brake shoes into the same position as the old shoes, making sure the pin the retainer clip attaches to protrudes through the mounting hole at the center of the brake shoes. Place the spring and retainer clip over the pin and place the brake shoe removal tool over the clip. Push down on the tool and rotate it clockwise until the clip locks into place.

6

Position the hook on one end of the return spring into the hole at the top of one of the brake shoes. Use the brake spring pliers to stretch the spring until the hook in the other end of the spring is positioned into the hole at the top of the other brake shoe. Slide the brake drum back over the hub.

7

Repeat the above steps for the other rear wheel. Replace the wheels and tighten the lug nuts with a lug wrench in a clockwise direction. Raise the rear of the vehicle with a hydraulic jack and remove the jack stands from under the vehicle. Lower the vehicle and remove the hydraulic jack.
