I noticed the pattern on the disk in the upper photo shows 5 discolored areas, coinciding roughly between the 5 bolt mounting locations. I’ve never heard of such a problem, so I’m just speculating wildly. Could this have something to do with the right wheel axle spacer or the mounting lugs for the brake caliper? Could the caliper somehow be severely offset from the plane of the disk? Does the wheel spin freely when the brake is not applied?
