Brakes rely on friction to do their job, but the friction can eventually erode the materials used in the braking systems. With that in mind, it’s a good idea to understand how long your brake pads will last before they need to be replaced. Under normal conditions, your brake pads should last 30,000 to 60,000 miles; however, driving in hilly areas, stop-and-go traffic, and aggressive circumstances can lower this estimate. By keeping your driving habits in mind and watching out for signs of trouble in your braking system, you can avoid the problems caused by worn brake pads.
