Here's a great video that explains it very well. The most important point is getting the inner pad as close to the disc without rubbing, then set the outer pad to preference. Once BB7 are set up correctly all it takes is occasional adjustments of the pads for wear just like rim brakes. When I ride lift assist in Vail I adjust them at lunch. On my road bike after 2000 miles they're still untouched.

When I worked at an LBS none of the other mechanics knew how to adjust BB7s. Most new bikes all come with hydros, bleeding brakes is much more common than setting up BB7s.
