(Did you notice how the rear breaks wear out faster than the front. Is this normal?)
No - my front's wear out slightly faster. I think I read a post that if your rears wear out fast, it's because of a stuck rear ABS valve. You might check on that, because it means that your rear brakes could be dragging, reducing fuel economy, etc.
Did anyone notice, if they have the AWD v8, that the inside front pads are larger than the rotor surface, and rub the hub area? I notice this eery time, because the inside pads have a 1/2 inch wide groove on the inside edge that is deeper than the rest of the pad. It is getting less prominent, as the pads are gradually polishing down this area on the rotor. I've checked OEM pads, Albany and Raybestos and they all overlap the polished rotor surface like this. The outboard pads don't tho, only the inside ones. Wierd
