brakes not working as expected....HELP

[Steve-W]

As you can read in my build thread (link in my signature)
I changed my new MBC and Booster for an old one I had laying around, because it turned out that the new one is for a Nova or something simular small. (that takes care of one problem)
But it turned out the MBC of the other set was broken, because whatever I tried I couldn't get any brake pressure.

so now I mounted a factory referbished MBC..but again no pressure after breeding the brakes extensively.. assuming the MBC is not broken, the only other conclusion I can think of is air in the system...but where?? we pumped over half a gallon of brake fluid through the system...

could the brake distrubutor play havoc? I plan on bypassing it and see if that will give any result.

we took apart the broken MBC just to see what the inside is like and I have question, why do the two chambers have different springs? when I see this I wonder if a brake distributor is still necessary?
