I just bought a used but like new Schwinn Fairhaven for my fiancés daughter. Making some adjustments on it i noticed back brakes were not working at all. Looking for what was wrong I noticed the top of the right brake arm at the rear wheel was hitting the rear rack that's welded to the frame and not letting it travel so the pad could contact the rim. Nothing is bent and there is no adjustment i see that can correct this. It looks to be from the factory like this. After fiddling with the cable and the pad adjusters I see no way this can be corrected. the left side arm just barley clears. The pads do not appear to have excessive wear that would make difference. And thoughts on how to get rear brakes functional?
