There is a pretty good explanation on the sram (avid) site, but here is a summary (from memory) assuming you already have cable length set correctly.
(1) Loosen the bolts that hold the caliper to the mount bracket.
(2) Hand turn both pad adjuster dials clockwise to tighten them against the rotor. Adjust back and forth until rotor is 1/3 from outside and 2/3 from inside (off center) in caliper slot.
(3) Tighten caliper mounting bolts to recommended torque setting
(4) Back off each pad adjuster about 3 clicks. Play around a bit to get minimal drag on the rotor but still have strong braking force well before lever is half way squeezed.
(5) As pads wear, take up slack by tightening pad adjuster knobs. Do not use cable adjusters to adjust for pad wear as that will screw you up.
I love my bb7s!!
