Yes another brake bleeding question....

[elks]

So here is where I am at... I have replaced the rotors, and drums, new pads front and rear. I also upgraded with a new master cylinder and booster from a 1 ton. I have the switched as the cylinder as per the swap write up. In the process I have pulled all bleeders, cleaned and or replaced with new and cleaned the bleed holes in the calipers. etc.

Here is where I am now... I have bleed the Master cylinder and am getting ready to start on the wheels.

My concern it that my proportioning valve is right up next to my MC. when I swapped out/cleaned all my bleeders, I am sure I ran the fluid down. How should I go about bleeding the system now?

Should I hook up the lines from the master to the proportioning valve then let the rear gravity feed. then open the front and let it gravity feed.

Or can I just hook it all up and use the wife to go 1/2 down, open to floor hold etc....

I am just not sure as my lines are close to empty.
