On my Cannondale 2.8, brand new 105 rear brake calipers are having a problem. When installed, the brake shoe, metal/plastic that holds the pads, is rubbing firmly against the seat stay on both sides. How do I get rid of this problem?
Do I need to install a really thick washer on the caliper installation bolt?
