I tried removing the piston on my SLX, but after I took the lever off, the pin behind the piston will not pull out of the lever body. It looks machined so that it wont come out. Is that the same as XT? Is there a way to get it out? OH,I just pushed it in and twisted it, then it comes out!! I just need some fine circlip pliers or something to get the (6) screw out OK, done!
