Push the drum back onto the brake assembly. Ideally, the drum should provide some resistance, but not enough that you cannot push the drums on by hand. If the drums are too tight, then remove the drum and push the adjuster back upward about four to five clicks. If the drum slides on with no resistance, then remove the drum and push the adjuster downward four to five clicks. Repeat this step until the drum provides some resistance when installing. Install the drum back onto the rear brake assembly.

Some vehicle manufacturers equip the vehicle with a "self adjuster" for the star wheel adjuster. The self adjuster is a lever that expands the star wheel adjuster when the parking brake is engaged, and the vehicle is driven in reverse. This process of self adjusting brakes is not recommended, as it could cause damage to parking brake components, as well as causing rear brakes to become over tightened. Performing the steps in this article to complete a clean and adjust on the rear brakes of your truck is the best way to ensure you are getting a quality and accurate brake adjustment.
