Okay, so now what is the verdict? I haven't read every post in this thread, but almost all of them but I thought I read the rotor DIDN'T have to be pressed off, is that right?

If so, just replacing bolts with better bolts/nuts and torquing to spec should take care of the major problem at this point or is there something else I'm missing?

Are the uprights machined out of Stainless or are they hard aluminum? If they are stainless, I would stay away from Stainless fasteners as they will gall and possibly damage the part next time they have to be removed. Go with a grade 8.9 Metric bolt, possibly in black oxide coating and a good hardened washer. In this particular case, I wouldn't use nylock nuts, rather I would use the Metal crimped locking nuts as I've seen the nylock lose some of their grip on the bolt over time with heat, abuse, etc damageing them.
