You guys are doing it wrong. Tech 2 scanner...One man bleeding and let the ABS pump do the work for you using the brake bleed function in the tech 2! Its fast and works great.

It's only a short trip to Oregon from Houston. Hope you have tire chains for the passes.

My pump method also incorporates cycling the key at specific times with the pedal stroke, and I ain't about to try to explain this to a helper when I can do it all by myself in a fraction of the time.
I crack the bleeder, slip on the clear tubing, work the pedal and key while watching the fluid in the tubing with my GoPro sync'ed to my phone, check the reservoir, etc. I can replace the fluid in the entire system and bleed it in about 30 minutes by myself.
Hey Livebai8, take a look at my post below. I think it will help with a couple of basics and make your task quite a bit easier.

I have an opportunity to use a pneumatic brake bleeder once I get to this point. Who's used one? How did it fair? Was easier than is it manual bleeder? Also...should I empty the fluid reservoir and fill will with new fluid before bleeding? I'm changing the rear rubber hoses tonthe calipers too.

i use a turkey baster to suck out the old fluid, then fill it up with new fluid.
never used that type of bleeder, but they will will do the job as well.

Do you empty the reservoir completely or leave just a bit and fill with new and refill as needed until all bled?

Your will get clean fresh fluid faster if you do suck the bulk of the old from the res and fill with new.
"... the bulk ..." is the key phrase here. Never let your master cylinder run dry unless you're prepared to bleed it by itself. Leave a little fluid in the reservoir, covering the valves, and keep topping it off if your tool doesn't do that by design.

like everyone else said, you can leave a bit in there. while your doing the calipers and lines make sure the master is full and dont drain out on ya. it will slow drain on you.

If you're doing a full flush then you might want to consider using DOT 4 fluid. If you're at DOT 3 now.

DOT 4 has a higher boiling point than DOT 3 so it’s more heat resistant.
It is has higher viscosity so it works better with antilock brakes.
