    XTR Disk Brake Question

    Hello all. I am running XTR 970 disk brakes on my bike. When I am off the bike and I hit the rear brake, the bike shakes a lot when I drag it next to me. I have swapped the pads from the front to the back and that did not do the trick. I have tried braking at high speeds to try to break the pads in and that did not work.

    If anyone has any suggestions, I will be happy to try. I have not bled the line, but don't want to unless I have to. Can it be a hub problem or an xtr rotor problem?

    Can't really help.

    Is everything tight/secure? Loose pads maybe?

    Last resort, go to LBS.

    What does it do when you are riding?

    Make sure all rotor bolts are tight and see if the wheel has any play at the hub.

    I took the caliper off and reinstalled. It seems better now. When I ride, it seems to slide to one of the sides if I hit the rear brake hard.

    The rotor has the cenerlock so that is on nice and tight.

    When I have the bike on the repair stand, and I hold the rear brake down, I am able to move the wheel. It does not lock in place very well.

    Thanks for the replies.

    Sounds like you're just locking up the rear wheel- nothing to be worried about, you just don't need to hit the brakes so hard.
