I had the exact same issue with my metal brake disc. It took me a very long time to finaly figure what was going on because every 1/2 turn it would bind up. I thought i had my mesh wrong but after remeshing maybe 8 times with no luck i looked at the brake which WAS rotating freely but the little metal tabs were catching. I cut them right off and now i have no problems. Actually between that and the alloy brake seat, i have to be careful not to give it full brake or it will flip forwards on me
I hope your problem is that simple RogersRacing. Although if it is you may just feel like banging your head against a wall repeatedly.
Good luck
