Almost all cars use rear brakes for stability and Traction control. The wife's Range Rover Supercharged w/ Brembo's has had 2 rear changes in 52K miles and 20K of that is Highway. Audi SQ5 has eaten rear brakes due to the kid driving it like it is a track car. I replaced the Rears on the Raptor at 51k and I do not drive the truck like a track car.
