I have a method that has always worked for me. I have never had a problem result from it, but it is my own invention. In fact it works so well I don't bleed any other way. I put worn out pads in the caliper being bled and then use the brake pedal to pump the caliper pistons all the way out. Crack the bleeder screw (or screws) and push the caliper pistons in until brake fluid comes out of the bleeders and close them. You don't need to bleed much fluid out since the air will always be on top in the caliper. All the air should be out of the caliper with one cycle, but keep repeating this until you get no more air out of the bleeders from the brake lines. Then just pump the caliper pistons out again and then push them back in with the bleeder screws closed. This will push any remaining air in the lines and in the MC into the MC resevoir.

I think this technique works so well because you are not trying to push air bubbles down where they don't want to go. I also like it because it does not require any tools or an assistant to pump the brake pedal, and you don't risk damaging the seals in the MC by pushing the pedal too far.
