Replacing the adjusting hole plug
The adjusting hole sits in the backing plate of a rear drum brake and gives access to the star wheel adjuster. A rubber plug keeps dirt, water and road spray out of that opening, which helps the adjuster turn freely and reduces corrosion on the threads. When the plug is missing, cracked or hardened, moisture can get in and the adjuster may seize over time, leaving the shoes too far from the drum.
Plugs usually come out during brake service, because the drum must be removed or the adjuster turned through the hole. Pushing a new plug in fully, without tearing it, keeps the seal intact. Clean the hole and the adjuster threads before fitting, and check that the plug sits flush so it does not work loose on rough roads. If the rubber is brittle or split, replace it rather than reusing it.
- Replace plugs that are cracked, split or hardened
- Clean the adjusting hole before fitting the new plug
- Seat the plug fully so it does not work loose
- Adjust the rear brakes after drum work and test the pedal
