I have heard that on lots of cars with 4 wheel disc brakes, that frequently they will wear 2 sets of rear pads to one set of front pads. I thought it was just the opposite. Shouldn't the fronts wear faster? How is this explained?The reason is that almost always the semi-metallic brake pads are used in the front and organic pads in the rear. It turns out that the semi-metallic's wear better than the organics, meaning they last longer! Organic pads are softer and tend to wear out faster, but they do cut down on noise. However you will see variations of this and some cars now use ceramic pads on all four corners.
