I have attached for you below the brake adjustment procedure for Lippert self-adjusting braking assemblies.

1. Jack up coach and secure on adequate capacity jack stands. Follow coach manufacturer’s recommendations for lifting and supporting the coach. Make sure the wheel and drum rotates freely.
2. Remove the rubber plug from the adjusting slot on the bottom of the brake backing plate (Fig. 2).
3. Insert a screwdriver or standard adjusting tool into the adjusting slot to rotate the starwheel (Fig. 3) of the adjuster assembly to expand the brake shoes. Adjust the brake shoes out until the pressure of the linings against the drum makes the wheel very difficult to turn.
4. Then rotate the starwheel in the opposite direction until the wheel turns freely with a slight lining drag.
Note: A second screwdriver will be needed to push the auto adjusting lever away from the starwheel so that the starwheel can be rotated backwards.
5. Replace the rubber plug in the adjusting slot and lower the wheel to the ground.
6. Repeat the above procedure on all brakes. For best results, the brakes should all be set at the same clearance.

If adjusting the braking assemblies does not fix your issue then you may have a bad magnet or some of the components have been damaged in which case your next best option would be replacement, part # AKEBRK-35-SA for 3,500 lb axles or part # AKEBRK-6 for 5,200 to 7,000 lb axles.
