Brake Reline Procedure

SUGGESTED BRAKE RELINING PROCEDURES

1. Remove the drum and inspect for wear, heat-checks, cracks, and evidence of overheating.
2. Inspect the brake lining for even wear on both shoes, across the axle, all brakes on a tandem. Uneven wear indicates a problem.
3. Inspect the rollers, pins, bushings, etc. for uneven wear. These hardware components should be discarded with the springs, but uneven wear will pinpoint problem areas in the foundation brake.
4. Inspect the spider, brackets and air chamber for damage and security.
5. Inspect the cam bushings, cam shaft and slack adjuster for wear. It is recommended that the cam bushings be replaced at each reline, especially if there is an indication of uneven lining wear.
6. Replace the lining with material that is suited to the application by GAWR, A/L factor and tire size.
7. Inspect the shoe for stretch, warping, anchor pin fit and roller fit.
8. Install all new hardware, bushings and other components to ensure they will operate satisfactorily through the next reline.
9. Adjust the brakes in accordance with the manufacturer’s recommendation.
10. Road test the vehicle to ensure proper brake operation. It is recommended that the brakes be applied at high input pressure without locking the wheels. A minimum of twenty (20) stops should be made.
11. Let the brakes cool and check adjustments.
