If your car makes a harsh grinding sound every time you press the brake pedal, don't wait — that noise is often metal grinding on metal, and it gets more dangerous and more expensive by the day.
The most common cause: worn-out brake pads
Brake pads have a friction material that wears down over time. When it's gone, the metal backing plate contacts the rotor directly — producing that grinding or growling sound. At this point you're not just losing braking power; you're destroying your rotors, turning a routine pad replacement into a far bigger bill.
Other causes of grinding
- Debris caught in the brakes: a rock or road grit can lodge against the rotor (common after Chicago's salty winters).
- Worn rotors or hardware: rusted or scored rotors and failed shims can grind.
- Lack of lubrication on hardware: dry caliper guide pins can cause noise.
What the fix looks like
Inspection may include pad thickness, rotor condition and brake hardware. Ask for the findings, applicable charges and a vehicle-specific estimate before authorizing work. See our brake repair service for details.
Frequently Asked Questions
Why do my brakes grind when I stop?
Worn brake pads and metal contact with the rotor are common possibilities. Debris or worn rotors can also cause grinding, so prompt inspection is important.
Can I still drive with grinding brakes?
Limit driving and arrange prompt inspection. Grinding can mean reduced braking and continuing to drive can increase component damage and repair scope.
How much will it cost to fix grinding brakes?
Cost depends on the inspection findings, vehicle, affected components, parts and labor. Request a vehicle-specific estimate before authorizing work.
