Just picked up a 2000 1150GS, going through the servicing etc and finding the front brakes have some movement I though fine (A-la K1100 floating disks). Turns out AFAIK that they are not fully floating! 
So on 1 disk it is pretty rigid (radial movement) but the other side can be moved and 'klonks' when rocking on the front brake. I've had a search but not realy any wiser!
1.
Is my front hub worn?
2.
Is there a simple fix?
Cheers.
