Drum Brake Automatic Adjuster
WARNING: This page is about a different car, the 2009 Dodge Caliber. However, it is still accessible from the selected car via links, so may be relevant.
To properly test the drum brake automatic adjuster, the aid of a helper inside the vehicle to apply the brakes will be necessary.
- Raise and support the vehicle. Refer to Vehicle Quick Reference/Hoisting - Standard Procedure .
- Remove the access plug from the rear adjustment slot in each brake support plate.
- Insert a thin screwdriver in the adjustment slot and push back the adjustment lever. With the lever in this position, back the star wheel adjustment off approximately 10 notches. This will eliminate the possibility that the brake is at full adjustment, and can be adjusted no further.
- Remove the screwdriver from the adjustment slot.
- Watch the star wheel through the adjustment slot, while a helper applies the brake pedal. As the brake shoes apply, the adjustment lever should move downward, turning the star wheel. A definite rotation of the adjuster star wheel can be observed if the automatic adjuster is working properly.
- If the star wheel is operating properly, readjust the brakes. See Brakes/Hydraulic/Mechanical/SHOES, Brake - Adjustments .
- Reinstall the adjustment slot access plug.
- Lower the vehicle.
If the star wheel does not move as indicated, the brake drum needs to be removed and further inspection of the rear brakes is necessary.
