But if the pistons are not moving, would that not simply result in poor braking, rather than uneven wear?
The worn pads are the ones closest to the pistons, btw.
The guide pins in the carrier are in good shape, so I'm at a bit of a loss. If the guide pins were sticking, it would make sense to me, but they don't seem to be doing so.
Interesting, in my experience it's the other way around. I've used two sets of EBC RP-1 pads on the C6 and both have been poor, whilst I regularly use EBC discs (dimpled and grooved) with no issues. They're high carbon and seem to resist cracking pretty well.
