I fill the tank with 1.5 qts - pressure the system to 15 lbs - open all 4 - one wheel at a time - fluid is now flowing thru all 4 bleeders - not long after I open the left front - it's time to hit the right rear and tighten down.
You gotta move, but it works for me. Like I said above, I learned the concept from a pro brake shop. In their case, they had a real pressure bleeder that held alot of fluid. They would open all 4 and let the fluid flow down into a bucket under each wheel.
Tighest brake pedal I ever had.
