So I brought my car 2015 WRX in for its 12K mile service and the tech mentioned that my brakes are not wearing normally and that my fronts have 9mm left which my rears have 6mm left. He said that a 1~2mm difference can be expected, but usually the wear occurs towards the front. This makes sense as the weight is shifted forward when stopping, but what would make the rears wear down faster than the fronts? I asked the tech this and he just said, "your style of driving" is the cause, but could offer no other details. Does anyone have an idea what would cause this?
