Brake shoe linings attached to the shoes by rivets need replaced when worn to 1/32 inch of the rivet heads. Work on the brakes in pairs to maintain equal braking action on both sides of the car. Always replace the brake shoe linings on both of the front or rear tires at the same time, even when only one wheel lining needs replaced.
Take off the wheel and the brake drum. Note the assembly of the springs and retainers for future reference. Remove the retracting springs and the brake shoe retainers with brake spring pliers.2
Grab the shoes and lift them off the backing plate. Let them slide together. Disassemble the adjusting screw and spring. Lubricate the adjusting screw with a high-temperature lubricant after removal. Mark the front and rear shoe.3
Use a drill with an extra large bit to remove the old linings. Maintain the original size of the rivet holes.4
Clean the backing plate with a dry rag or an approved cleaner. Apply high-temperature lubricant lightly to the backing plate so the brake shoes don't squeak after assembly.5
Secure new brake shoe linings. Install the rivets, starting at the middle and working toward the ends. Rivets should hold the brake shoe lining securely without splitting near the rivet holes.6
Reassemble and test the brakes, making several low-speed stops to ensure that they work.
