I have a mighty-vac bleeder that I got at the local parts house which is pretty inexpensive. It's a hand vacuum pump which you plug into the bleeder valve. You pump up a vacuum and crack the bleeder valve until the pressure drops. I always pull out the old fluid from the reservoir to start with, put in fresh fluid and start the process. Bleed the furtherest from the reservoir first, then the next, the next, then the shortest (i.e. right rear, left rear, right front, left front). Always make sure the reservoir is kept full to avoid air. I also always like to do the old 2 person pump and crack the bleeders on all for corners for the last session though to make sure the air is all out even though it may not be necessay.
