Squeaking brakes is one of the most common problems car owners will face. Many different things can cause brakes to squeak but ultimately, all of them are created by the friction of the brakes rubbing against the tires. \
Brakes work by creating this friction but the friction causes heat and this can cause the noises you hear. WD-40, that seemingly miracle formula, can lubricate brake pads and rotors and reduce that squeaking noise. \
Apply WD-40 to brakes regularly and it will actually help extend the life of the brakes and reduce any squeaking noises you hear. \
