If you do use the above method as mentioned by the other posters, then after you have done this be sure and back out the inboard ajustment screw, red dial(the side closest to the bikes wheel) a click or two. BB7's are mechanical and only the outboard side brake pad moves, and the inboard pad doesnt move, its static. There is another way to do this that is explained in the Avid maintenance instructions-
First loosen the claiper ajustment screws, so that the caliper has a small amount of movement in it.
Screw the inboard ajustment screw clockwise, until the pad is snug against the disk rotor, then screw the outboard ajuster clockwise until it bites hard against the rotor. The wheel should now be hard to move, as the pads are hard against the rotor. Now tighten the caliper ajustment screws to secure the caliper and stop the caliper moving. The final step is to slacken the red dials off, 2 or 3 clicks anti clockwise on both sides should be enough, and thats it. I would advise that you check the Avid pdf instructions for this, as it will undoubtably be easier to understand than me!
