Message: >I'm looking for a tool to remove the bore cap on a xtr disc caliper.... it doesn't seem to exist according to the shimano sources I've contacted anyone have any ideas??? Or.... how do I remove the pistons to service the caliper. If you have a sticky piston and need to service it, what you should do is to -remove wheel and pads -hold one piston while compressing lever to expose the other piston but be careful not to pop piston out. -clean and apply a light coating of oil that will not harm seals -use a large flat screw driver to push piston back in. -repeat on other side if you really want to take the whole caliper, you can try a number 35t torx wrench but be warned, the calipar is not intended to be taken apart by the normal person. This may not work because Shimano applies a large amount of thread lock to the bore cap. Most of the ones that I have encountered will not come loose and I have even had some customers destroy the bore cap because it will not move and they try to force the wrench
