Brake pad FAQ.
How long do brake pads typically last?
Front brake pads last 30,000–70,000 miles, rear pads 40,000–80,000 miles. City driving wears pads 2–3× faster than highway driving. Performance pads on sports cars may only last 15,000–25,000 miles.
What are the signs brake pads need replacing?
Squealing when braking (wear indicator), grinding metal-on-metal sound (pads worn through), reduced braking performance, vibration when braking, or your brake warning light coming on. Don't wait for these — check pad thickness every 10,000 miles.
Should I replace all 4 brake pads at once?
At minimum, replace both pads on the same axle (both fronts or both rears) at the same time for even braking. Many mechanics recommend doing all 4 if rear pads are also low. Front pads wear faster — check them first.
