    Floating discs

    Just how floating should they be?
    Got a set of BSTs, complete overkill for the road I know, but hey when you’ve done 70k she needs some more bling. The discs have a small amount of movement in them. Not enough to foul the calipers, but more than on the standard wheels. Braking performance is as expected including a semi emergency stop but wondered what would be considered excessive. Bolts are torqued up correctly.

    Thanks. Only get noise when hard braking to a stop.

    Re: Floating discs

    So floating forward and backwards.... absolute ZERO movement. Should fail MOT if they do.

    Side to side, 3-5 mm max but it takes lot more than that for the disc to explode and crash the bike if you're unlucky.

    I see more cracks in discs than too much side float.
