getting linear pull brakes parallel front to back.
I am struggling with adding some linear pull brakes to my bike. Actually, I am adding an Xtracycle to my canti-equipped bridgestone, but the xtra only accepts linear pull or disc brakes. I picked up a set of Avid Single Digit 7 brakes to mount to the Xtracycle. I am having a problem getting the pads parallel to the rim. I am not talking about the arms being parallel and fiddling with the washer configuration, but the pads are not parallel front to back -- one pad has and extreme toe in and the other has an extreme toe out. The wheel looks pretty plum and true, so I donít think that is the problem. There doesnít seem to be an adjustment for this kind of configuration. Any help is appreciated.
