What's the real way to bleed if you disconnect just the rear brake lines at the calipers and the lines drain out a lot of fluid?

The GM manual says TO PRESSURE BLEED:
Right rear then
Left rear then
Attach hose to the right front wheel bleeder valve, turn ignition to RUN, open the bleeder valve, apply brakes until BRAKE light comes on.
Close right front bleeder valve.
Bleed ABS modulator front and rear bleeder valves then
Repeat rear wheel bleeding process again then
Bleed right front
Bleed Left front
Turn engine to RUN and check pedal pressure. Done.

Then then GM service manual says TO PRESSURE FLUSH:
Bleed ABS modulator front and rear valves till fluid is clear then
Right rear
Left front
Right front
Left rear

Then GM manual says TO MANUAL FLUSH (using the pedal):
Right rear
Left Front
Right front
Left rear

I will be using the Motive Products # 0108 Pressure $55 bleeding kit. Power Bleeder

I really Don't think it matters what order you go in. I know I don't go by any order. But I do know that they are connected Left rear to Right front and Left front to Right rear so you pretty much have to bleed the whole system when you take a caliper off.

Thats how its supposed to be done. Start with the farthest from the master and work your way closer. This will work out all the air bubbles.

That's what I thought too. The GM sequence definitely talks (in the book) alot about the ABS modulator except when doing a "Flush".
