    Help disc brake rub

    I have hayes carbon disc brakes. recently the brakes started to rub only when the bike is goping side to side. The brakes dont rub on the stand or just pedaling in a straight line. Although when climbing or sprinting, the front brakes rub. PLEASE HELP/ I tried resetting the wheel and adjusting the caliper, no help/.

    Sounds like your getting flex possibly from the QR or spokes.

    I don't think this would be from loose spokes. If the spokes are loose, the rim would move laterally but the rotor is attached to the hub, not the rim.

    Is it front or rear that is rubbing? Did you change anything?

    I agree it could be that you're not tightening your QR as much. Try to clamp that down a bit more if you can but it's also possible that your rotor has gone slightly out of true. Not enought that it rubs on straightaways but when turning, a slight bit of flex on your fork or rear end is causing this small warp in the rotor to rub the pads.

    Spin the wheels slowly and watch the rotor to see if it moves within the caliper.

    What hub and QR are you using & how old are they.

    brake rub

    I bet its your rotor. I had the same problem last week. Finally brought it into my lbs and thats what it was, the rotor. Had to be straightened. Try that.

    Is there any play in your fork? What fork are you running?

    I have a fox 100RL and a mavicx cross ride wheelset. They are both fairly new- 6 months or less.

    larger rotors 7-inch and up will sometimes make that "ching" sound in the front when turning

    Swing by the LBS & see if they have a spare XT QR you can use as a test really quick to see if that resolves the problem.
