DOS: When you get the caliper repaired, be sure to put the spring that should come with new pads in, to help push the pads back when the brake lever is released. On adjustment, Avid says to loosen the caliper mounting bolts, then turn the inner adjusting screw and outer adjusting screw until the rotor is 'pinched' between the pads, with 1/3 of the space between rotor and caliper on the inside, 2/3 space to the outside. BB7's are 'single piston'--meaning that only the outer pad moves when lever is pulled. the 1/3-2/3 spacing helps keep rotor 'warping' to a minimum. After tightening the mounting screws, back inner and outer adjustments until the pads JUST clear the rotor. Now you should be good to go.
