Hello, new to the forum and to trials. Recently purchased a 2001 Rev 3 270 and have recently noticed a definite "clunk" in the front. Thought it was the head bearings, but further research investigation has made me find that the front disk is rotating in its mounts. ( I'd say I can rotate it back and forth about a millimeter on the outside edge.) I know they are supposed to be floating discs, but that much? Any specs as to how much play (I can't find any). Lastly, is the remedy new spacers, or ?

Thanks in advance for the help.

Double check the two mounting bolts on the brake and also the disc. And it is `normal`.

My Techno was doing this and I replaced the bushings and the bolts that the disc is mounted with and it took 90% of the play out. Be careful when taking out the bolts as some are locktighted in with red locktight and must be heated slightly to release the locktight and not break the bolts.
