How do I adjust my drum brakes?
Since the brakes do not self-adjust, there is a certain method to be used regularly. First, you must elevate the subject wheel and access the adjuster by removing the rubber plug at the 6 o'clock position on the rear of the backing plate. Next, with the wheel rotating in the forward direction of trailer travel, you must tighten the adjuster until the wheel stops and cannot be rotated by hand. Then release the adjuster tension until wheel spins one full revolution after a rotational spin force is applied by hand. Repeat the procedure for each wheel on the trailer equipped with brakes. It is critical to adjust the brakes on a regular basis.
