Having upgraded to Juicy 3's, I have continual problems with rotor rub on the front but no problem at all with the rear. I keep having to reset the front after every ride or every time I take ot the front wheel. Any ideas?

    check the hub for play. check the fork for flex.

    set the caliper up correctly. (ie not over filled)

    Rubbing constantly or only when at high speed? Also is it rubbing the whole rotor or just a section?

    Constantly rubbing & any speed. I can get it to run free for a while but any ride over anything rough will bring it back in a short while.

    Does it happen when you go round corners more?

    I've had a similar problem with my Shimano ones when i went round corners after it was set up correctly and it wasnt until later i realised there where some loose wheel bearings to play havoc with me.

    If they're new pads in there give them a bit of time to wear out a little bit. Unlike Shimano brakes they dont have the servo control. It might even be a slightly warped disc or your front wheel might not be tightly in. Ive accidently stuck my wheel in loose braked quite hard and next thing i know my wheel isnt straight and my disc is rubbing.

    Push the piston back, and bed them in. Also check there's no muck in the caliper. Mine make an awful racket when mud gets in them.
