^ Which is why you need a really good seal between the cap & the MC. I had the same concerns until I tried it -- IMHO, pressure bleeding works SO much better and is faster than vacuum bleeding. I've used the Mityvac hand pump vacuum method before and won't be going back - I can get a rock hard pedal via pressure bleeding in a fraction of the time it took me with the Mityvac. And no sore hands from the repetitive hand pump action.

Pressure bleeding works very well with only 2~5 PSI pressure; just enough to push the air bubbles & fluid out the bleeder screws without risk of blowing any seals. So if you buy or build one for yourself, just make sure it has a gauge.
