Brakes form an integral part of safety infrastructure in your car. The brakes system is composed of brake pads and brake rotors. The pads are positioned on either side of a moving rotor on your axle. When you press the brake pedal, the pads are squeezed against the spinning rotor, slowing the car. If you hear the brakes squeal, the pads are close to or no longer have enough braking material to properly slow the vehicle. On the other hand, if you hear a grinding noise while driving, it is possible that the pads are no longer viable and do not have any material left. What you are hearing is the metal of the backing plate of the brake pad touching the rotor. This can be dangerous and should be inspected immediately. Whether you hear a squeal or a grind, please feel free to visit Big Bend Auto Repair and have our trained technicians inspect your brakes.
