Hi everyone..

1 day after replacing the belt on my xb9 I noticed a groaning coming from the brakes after removing the rear calliper I note the disc is physically binding against the mount, I cant see any warp in the disc but any one have any idea what would cause this? the bearing appear to be intact not sure what allow the wheel to travel the needed space to let the disc come into contact with "perch" of the caliper
thanks
Ned
