Bill, I sell these and I also have access to replacement pad sets and rotors.
 However they are so new (only available the last couple of years) that I
have never had anyone need new rotors yet and only a couple of customers
bought extra pads for when the original set they had wore out.

Thanks,
Ken Wilford
