Brake repair and what you need to know
You should check your brake fluid levels when your brake light goes on; this typically indicates that your fluid is low and your brakes should be checked over by a certified technician. If you see or smell brake fluid, get your car to a technician immediately as that indicates the presence of a leak. A vibrating wheel or brake pedal usually points to rotor surface issues and brakes that continue to squeal after you release the brake pedal means that the wear indicators are scraping against the rotors. The grinding or growling sounds that metal on metal makes is a clear signal that your brake pads have completely worn away. Experts strongly recommend that you have your brakes checked as soon as you sense that something is amiss.
