I made myself a siphon bleeder.... basically a "hookah" with clear tygon tubing. The vacuum I create sucking on it can bleed the brakes. One advantage with vacuum bleeding is that any bubbles are enlarged and stand a better chance of being drawn out of the system than with pressure-bleeding systems. The main drawback is that 9 times out of 10 too much air will be drawn past the bleeder screw threads to be effective, and I have to resort to the "two-man" system. I understand this air past the threads - if left there - can be a serious problem for a system with ABS.
(I wonder what the neighbors think seeing me doing the brakes with a hookah in my mouth!)
