REMOVAL & INSTALLATION
See Figures 1 and 2
- Remove the brake drum.
- Remove the long brake tension (retracting) springs. These have hooks on each end, but you should be able to get them off with a pair of needle nose pliers. Remove the holddown springs with a brake tool. You can make due with some other tool, but it won't be easy. Pull out the spring pin from the rear, and remove the shoes.
If the brake shoes are to be reused, mark them so that they may be returned to their original locations.
- Clean the backing plate with a wire brush.
- Inspect the brake springs for deformation and weakness, replace any parts found to be defective.
- Check the brake linings for wear. The factory limit is 1mm measured at both ends and middle of the shoe. If the limit is exceeded, replace both brake shoes.
This measurement may disagree with your state inspection laws.
- Check to see that no grease or brake fluid is leaking onto the backing plate or the shoes. Fresh grease on the backing plate may indicate a faulty seal in the hub. Brake fluid leakage can be traced to the wheel cylinder or brake line. If there is any leakage, rebuild the wheel cylinders or replace the brake lines. DO NOT DELAY, as a brake failure may result.
A small trace of fluid may be present to act as a lubricant for the wheel cylinder pistons.
- Before proceeding to the installation of the brake shoes, coat all the points of contact on the backing plate with a film of multipurpose grease.
Install the shoes in the following manner:
- Fit the upper and lower shoes onto the grooves on the wheel cylinders and adjusting bolts. Install the spring pins and the retaining springs with the aid of a brake spring tool.
- Hook the brake shoe tension springs on the upper and lower shoes.
- Install the drum and adjust the brakes.
