Grinding noise when braking
A harsh metallic grinding when you brake usually means the pad friction material is gone and the steel backing plate is cutting into the disc.
AreaBrakes & steering
UrgencyHigh
Can I keep driving? Limit driving and diagnose promptly. Continued driving can cause damage, stalling or limp mode.
Common causes
Pads worn down to the backing plate
Braking power drops, and the disc is destroyed quickly.
Debris between pad and disc
A stone caught in the brake can grind constantly.
Badly rusted discs
After the car has stood for a long time, heavy rust on the discs grinds until it wears off.
Seized caliper or worn wheel bearing
Grinding that continues when not braking points elsewhere.
What to check
- Inspect pads and discs as soon as possible.
- If the pad material is gone, replace pads and discs together.
- Check that the caliper slides move freely.
