How do I stop my drum brakes from squeaking?
Lack of lubrication on drum backing plate: In a drum brake system, the shoes and drum mount to a backing plate. If the backing plate isn’t lubricated at the shoe contact pads, you may hear a squealing noise. Solution: Remove the drum and shoes and lubricate the backing plate.
What does it mean when drum brakes squeak?
If your vehicle has drum brakes and you hear a squeal, it’s a good warning sign that your brakes need lubrication. Once the contact points no longer have lubrication, the metal starts to rust. That causes the shoes to scrape on the backing plate and thus squeal.
Why do my Subaru brakes squeak?
Brake pads are usually embedded with a little metal spring. As they start to wear down, the more the spring is exposed. When the pads become too thin, the rotors will rub against the spring and cause a high-pitched squealing noise. That sound is your warning to get the pads replaced.
Can WD 40 stop brakes squeaking?
WD40 should not be put on your brakes since it can reduce friction where it is needed and even break down and damage brake components. While spraying WD40 may temporarily reduce a brake squeal or squeak, it could also cause the brakes not to function correctly when you need them most.
Do squeaky brakes mean they need to be replaced?
Squealing. Squealing or squeaking noises usually indicate that your brake pads require replacement. Some brake pads are equipped with wear indicators in the form of small steel clips, which make a squealing sound when the pad has worn down. Glazing on the brake pads can also cause them to squeal.

Do you need to lubricate drum brakes?
