How Long Do Brakes Last In Cars. Modern cars use disc brakes, and those discs (aka rotors) need something to squeeze them so you can slow down. Car brake pads last around 50,000 miles on average, but this can vary depending on a large range.
Usually, the brake pads need replacing regularly because they wear out over time. The brakes must overcome dynamic inertia (the car in motion) and impose static inertia (make the car come to a stop).
