I can not get the air out of my brake lines.

So I am planning on driving from NC to CA Wednesday and the only thing I have left to really do is bleed the brakes.
I put a new master cylinder on it and have no issues with the fronts, but the rears just keep blowing bubbles.
I have installed speed bleeders into the wheel cylinders, but every time I think I have all the air out, more comes out.

Things I did get done this weekend:
New KYB shocks all around, the old ones were labelled Delco and had zero rebound.
Replaced the carpeting with tiled paneling from the entry door to the top of the steps. Added insulation underneath.
Installed a Firestone air compressor and 15L air tank.
Installed Xantrex Inverter/Converter and additional breaker box.
Installed an electronic safe in one of the cabinets.

Things I did since purchasing:
Repaired leaky fresh water tank.
Replaced both mufflers with Dynomax Super Turbos.
Installed engine compartment side vents.
Built battery tray for drivers side.
Built larger battery tray for passenger side.
Moved house batteries to drivers side.
Replaced upper seal in steering gear box.
Installed air suspension seats.
Patched holes in roof.
Replaced external transmission cooler and added external filter.
Relocated external fuel filter closer to tanks (was up front).
Installed H4 Headlight Assemblies and Sylvania Silverstar Ultra Bulbs.
Installed fresh air vent for driver. (Thanks JR)

I probably did more, just can not remember it at the moment.

So for the brakes, I did not use a tool on the proportioning valve, could that be my issue?
Or could I have a bad master cylinder?
