hope still have a few spares for the xc4 brakes and i think you can get the rebuild kit for the levers no problem it is the caliper end that could be hard to find spares for but they are out there, that brake didn't last long production wise. pads shouldn't be too hard to find with a bit of effort looking. spares for the pace fork just PM "justbackdated" on here, it's tim who used to be the actual pace service guy, he set up his own servicing company for older pace forks and can sort parts and service for almost any pace fork from back in the day, and he's recommendd by Pace themselves on their website, his company is Fork English.
