    Hey All- Does the front brake rotor on M2 supposed to be somewhat loose or "floating"? I am new to this bike but notice the alan bolts and nuts which hold the rotor on the hub, have some play in them. I tried tightening both the nut and alan head and they seem to be fully tight however there is still some play in them?

    Any help is appreciated

    That was a problem with the older 6 bolt front rotor setup, they updated them to a 9 bolt later. I have to upgrade my 98 s3 to the newer set up. Keep and eye on it. sells the newer set up if you need to see a picture.

    Eventually the carrier hub will fail, the material will fatigue and the rotor will no longer be attached. just the caliper holding it in the correct location.
    It is best to replace it. Take that from experience, Mine failed, pulled the wheel off and the disc itself dislodged from the hub, picked the newer style, and was never happier.

    There is a reason they call them "Floating" rotors. A small amount of play is absolutely normal. Check the FSM for the allowable amount of play. Sorry don't remember the figure off-hand.
