Only drum brakes need adjustment. The disc brakes don’t. But with weak rear brakes, the front brakes need to compensate all the braking power causing premature wearing and other problems.
Follow these steps:
- Determine if the brakes need adjustment. You do this by lifting the car on stands and rotating the rear wheels. If the rotating doesn’t stop before two turns the brakes need adjustment.
- Determine if you have self-adjusting rear brakes or not.
- If you don’t have self-adjusting brakes you start with removing the rubber plug from the backing plate porthole. The moment the plug is accessible use a screwdriver to press the star adjuster retainer pin with a screwdriver and adjust the star wheel until the shoes touch the drum. You stop adjusting the star wheel when after rotating the wheel one revolution it stops because of the drag.
- On a foreign car adjust the parking brake mechanism to adjust the rear drum brakes. You may either repeatedly apply or release the parking brake or there may be a lever in the drum braking system that you reposition. With the parking brake adjustment you may need to tighten the handle inside the car. Because many import cars have self-adjusting brakes, there’s not much you can do.
- Now that you’ve discovered your brake’s adjustment type, do this repeatedly and also try to use the hand brake each time you park.
