Car Grinding Noise When Braking: Causes and Costs
A grinding noise when braking almost always means worn brake pads — once the friction material wears away, the metal backing plate grinds directly against the brake disc. This is serious: your stopping distance is compromised and continued driving will damage the discs. Book a garage immediately.

Common questions about: Car Grinding Noise When Braking: Causes and Costs
Why does my car make a grinding noise when braking?
The most common cause is worn brake pads — once the pad material wears away, metal grinds against the brake disc. It can also be caused by a stone or debris caught in the calliper, a seized calliper, or badly corroded discs.
Is it safe to drive with grinding brakes?
No. Grinding brakes indicate severely worn or damaged components. Your stopping distance will be longer and the brakes could fail. Book a garage visit immediately — do not leave it.
How much does brake disc and pad replacement cost?
Front brake pads and discs on a typical UK family car cost £180–£350 at an independent garage (parts + labour). Rear brakes are often slightly cheaper. Premiums apply for large SUVs, performance cars, or if callipers need replacing.
Can I just replace brake pads without discs?
If the discs are scored or have worn below the minimum thickness, you must replace both together. Fitting new pads to worn discs reduces braking performance and causes rapid pad wear.
