Great write up.
The whole trick to bleeding brakes is patience.
Just make sure when you are done the pedal is as hard as a rock or you'll experience the effects of air in the system.
I generally don't use pressure systems.
I first vacuum out the master cylinder with my air powered bleeder assem. Then I fill with new fluid. This gets out any bad effects from the resevoir and prevents them from traveling in the system during the process.
Takes more of the old fluid out faster and makes the process easier.
I then regularly fill the M/C as I bleed each caliper.
I have my bride pump the pedal so I am sure I have bled out everything on each caliper.
Either way is fine though.

I forgot to refill the master and just attached the bleeder with two Qts of new fluid after I sucked out the old fluid, also forgot to pre pressurize it and just pumped it to 20lbs and bled all 4 calipers and still had a qrt in the bleeder when finished, pedal hard as a rock....

That's what I have used twice now, works like a charm, also for,those wondering about getting air in the system with this unit it does not!!
