    XT disc rub, & bleed questions

    So I am new to discs and I can't find a thread to address my issues. My front XT disc is rubbing and I can't get it to stop. I don't know if I need to bleed the brake or what, I guess what I am really asking is when do I need to bleed them and how do I know? Thanks for the help.

    Have you tried centering the caliper?

    There's this handy thing called the search.

    If it's an older 4 piston XT direct IS mount brake, you'll need shims to space the caliper inboard. If you need to move it outboard, you may need to face your tabs, use rotor shims, or slide a washer underneath the locknut of the hub.

    If it's the newer 2 piston brake, it's a post mount caliper (may be attached directly to post mount tabs or to an International Standard adapter). Loosen the two bolts that attach the caliper to the adapter (not the adapter to the frame/fork). The caliper should now be able to move side to side. Pump the lever a few times and then hold it. Tighten up those two bolts evenly a little at a time. Make sure the caliper does not shift while you are torquing down those bolts. It may take you a few tries to get it.

    So I guess the next question would be how to tell if its a 4 piston or 2 piston. They are on an 05 enduro pro. I tried the search but no thread I can find addressed the exact quesiton that I was asking, or maybe I'm a putz and just am not searching correctly.
