Rotor Clearance.

Hi. I have some Marzocchi Bomber All Mountain 3 forks and Avid Juicy 7 disc brakes with 180mm rotors and, what I have noticed is the rotor is very close to the fork leg maybe around 1mm at the closest point and it appears that at some stage the rotor must have been rubbing as there are abrasions to the paint of the leg. I'm sorry I can't get you a picture as the lense on my phones camera has condensation on it but, I will try with our lasses phone tonight. Is this something to be concerned about and at a later date I was hoping to replace these rotors with floating ones, is that possible?
Thanks Andy :)

    Silly idea, they are rubbish and will make it worse.

    What fork fitment type (qr/bolt) along with brake type (pm or is)?

    Normal quick release and the forks are post mount.

    Check the o.l.d on the hub is 100 mm.

    Visually check your posts are straight and the disc runs mostly true.

    be ware of floating rotors - the rivet that holds the steel rotor to the alloy central carrier sticks out further than a one piece steel rotor on some models so may may the rpoblem worse. e.g. Hope SAW cannot be used with Formula R1 brakes for this reason - Formula floating discs have the rivet flusth with the surface of the disc.
