Cleaning your brakes removes debris from rotors and pads, which can reduce squeaking noises. \
Brake cleaner is designed to be used on all parts of the brakes. That includes the pads, the rotors, the lining, the drums, and so on. \
When you apply brake cleaner, it should be sprayed directly on the front and back of the rotors. Use a microfiber cloth to wipe down the rotor after the cleaner has been applied. \
Specialized brake cleaner is formulated to work on brakes and it's made to cut through grease and other substances brakes commonly come into contact with. However, plain soap and water also work to clean brakes. \
