Grinding When Braking
Pull Over Now — Urgency 5/5Do not drive. Your braking ability is seriously compromised and you risk brake failure. Pull over safely and arrange for the car to be recovered or towed to a garage. This is general guidance — grinding brakes need professional attention immediately.
This is general guidance. Your situation may differ — when in doubt, don’t drive.
What does it sound like?
A harsh, grinding metal-on-metal sound when you press the brake pedal. It sounds like sandpaper on metal or two pieces of rough metal rubbing together. You might also feel vibration through the brake pedal or notice that the car takes longer to stop.
What could be causing it?
Less commonly, a stone or piece of debris can get caught between the pad and disc, but this usually dislodges itself quickly.
What should I do right now?
Stop driving as soon as you safely can. Do not keep driving with grinding brakes — every stop is damaging your brake discs, which are much more expensive to replace than pads alone. Call a mechanic or arrange a tow. If you absolutely must drive a very short distance, go slowly and leave lots of space.
