    Is the rotor straight?

    Is it occaional rubbing or constantly?

    Might need to use shims if its rubbing constantly (whole time the wheel spins)

    I mean use shims on the mount/rotor. Between where they touch the forks/hub.

    Leave them in there as well, don't take them out. Putting them behind the pads will only hae the effect of pushing the pistons further out

    Mine did that that, so i took them to the lbs- they used this little tool to straighten the disc. you may think the disc is fine, as i did- it looked straight, and i had constant rubbing, but it was the disk that was the problem it turned out :?

    yes replace pads and then use. there was no need to do anything else. If things were fine before.

    why?

    that will not help anything.

    do the rotors move when you pull the levers?
