As I was saying, the seals appear to move in and out fairly easily. The amount of dust on the seals in the picture is down to 2000 miles riding in one week with the pads rubbing the disc. Prior to my trip, I replaced the pads and gave the calipers and pistons a good clean. There was no sign of any marks on the pistons at that point, but I'd admit I can't be 100% sure as I only remove one piston (accidentally).
At the moment, I'm inclined to think it's down to the grooves in the calipers caused by the pads, but don't know how I'd go about flattening them again.
