How do you fix squeaky drum brakes?
- Analyze the brake squeal.
- Be sure new brakes are properly bedded.
- Install noise-reducing shims on the backs of your brake pads.
- Check that your brake pads are not worn out.
- Examine the brake pad and shoe linings to see if they are damaged or unevenly worn.
- Check the brake pad design.
Likewise, people ask, why are my new drum brakes squeaking?
Answer: Brake pads are the most likely problem. You probably have rear drum brakes and the noise you're hearing is most likely the brake shoes rubbing the backing plate. This movement is normal but your contact points probably no longer have any lubrication between the shoe and backing plate causing a squeaking noise.
Hereof, how do you lubricate drum brakes?
The parking brake usually uses the rear drum brakes in your car, so lubricate the parking brake cable and any linkages or moving parts. Make sure you lubricate the separator located about halfway up the shoe. Use lubricant anywhere you find metal-to-metal contact between moving parts, such as where the shoes slide.
Although WD-40 isn't a great lubricant, it does offer some lubrication. Putting ANYTHING lubricious on your brakes is a bad idea. WD-40 will evaporate off in a few days. If you can't wait that long, spray them down thoroughly with brake cleaner and let them dry.
