I use the Mity-vac, here's how I do the job. I prop the brake pedal down about an inch, this is to cover the vent in the master so fluid doesn't flow to the bleeders. Then, I take all 4 bleeders out and clean them with a wire wheel. Take silicone grease and apply it to the threads of the bleeders. This will seal against air leaks around the threads. Reinstall the bleeders hand tight. Un-prop the brake pedal. Use the right adapter for the bleeders( I think it's the 'B') and apply about 15" of vacuum. Crack the bleeders in this order; RR,LR,RF,LF and tighten them with a wrench when you're done. Make sure you keep the fluid topped off in between wheels. Oh, and use a very clean turkey baster to suck the old fluid out of the master's reservoir before starting the job.
