Some brake noises are normal, while others indicate problems requiring service. This is what the noises could mean:
- Grinding When caused by rust building up on the rotors, it's of little concern. The buildup can usually be removed, or sometimes it disappears after a few stops. If grinding persists, the problem could be more serious and should be addressed immediately.
- Loud squeals Disc brakes with wear indicators may produce a squeal,
indicating it's time to change the pads.
- Trace squeaks or squeals Semi-metallic brake linings can emit sound. Rain, humidity or cold brakes could be the source. If the problem persists, have the brakes checked.
- Clicking Sometimes accompanied by a slight pulsing in the brake pedal at low speeds, it's most likely the Anti-lock Braking System performing a harmless self-check.
