I noticed when I removed the studs this pattern on the back of the brake disk hub, it concerned me as if you look at the rust pattern the hub actually is installed where it can float when the studs are not torqued, the difference between the hub and the disk hole is .285", I understand floating rotors in the racing world but in the coach world this seem a bit weird so I set out to shim the disk hole so the stud will be dead center on the hole. I found that a craftsman socket is exact 1.25" OD so I put a socket on my mill with a 1 inch bit and drilled it out then cut into pieces .5" thick and placed them into the disk hole inserted new studs with a 22mm stud insertion tool and all is well.
