I am just about ready to junk a set of wheels on this bike http://www.ratrodbikes.com/forum/viewtopic.php?f=16&t=23600 The rear hub grinds when applying the brake and does a revolution and a half before it will go forward again, I have taken it apart and not sure if there is anything to adjust, it looked to have plenty of grease, and I believe the hub is a Hi stop or something less than quality. Thanks for any help you can offer.
