I'm adding disc brakes to my xtracycle, and I've purchased BB7s. In order for me to get the brake not to rub, the gap is so wide that the braking force is pretty much only good for slowing, not for stopping. I've looked online and followed the suggestions. I can get the gap spacing correct, and then I adjust the pads per the instructions, but then when I turn the wheel there is considerable rub. I think I'm just not getting the caliper aligned correctly. Can anyone give me some pointers on how to do this correctly?
Install with mtn levers (basic, no name ones), 203mm rotor 160 mm caliper adapter (per xtracycle's instructions). BB7 Mtn caliper.
