Brake pads are typically good for 30,000 to 70,000 miles. Many factors affect the number of miles brake pads last; some drivers must replace pads after just a few miles, while others use the same pads for over 100,000 miles.
The weight of the vehicle affects the wear of brake pads. Carrying extra weight in the trunk increases the momentum of the vehicle and the wear on the pads. Brake pads on vehicles that accumulate most of their miles on the highway last much longer than on vehicles that drive in stop-and-go traffic every day. Drivers who accelerate and decelerate slowly use less of the brake pad material than those who make sudden starts and stops.
