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
We start by inspecting pad thickness, rotor condition, and the hardware. If you caught it early, it may just be pads. If the rotors are scored, they'll need resurfacing or replacement. Either way, we'll show you the worn parts and give you a written estimate first. See our brake repair service for details.
Frequently Asked Questions
Why do my brakes grind when I stop?
Most often your brake pads are worn out and the metal backing is contacting the rotor. It can also be debris or worn rotors. Have it inspected promptly — it affects your stopping ability.
Can I still drive with grinding brakes?
Only minimally, and carefully. Grinding means reduced braking and ongoing rotor damage. The longer you wait, the more expensive the repair becomes.
How much will it cost to fix grinding brakes?
If it's just pads, it's a routine job. If the rotors are damaged from driving on metal, they'll need replacement too. We give a written estimate before any work.
