Big Bolt John Go to the first joint in your steel line after leaving the master cylinder,with the master cylinder full you should be able to just gush fluid out of that loosened joint ! Master cylinder will lose fluid. If it will do that go on to the next joint same thing. If it wont do that go back and find why that master cylinder wont pump. It should do this even if not piped right on downstream. I take a new bleeder drill thru it tighten into any cylinder,run farm store clear tubing on the floor back around to the open master cylinder lid. You can then circulate fluid getting air out as you go,if you have firewall mount master cylinder will need the aid of a helper who understands what you are doing. just helped my neighbor with this on a 51 ferd even-- took us 45 minutes had a full solid pedal
One other thing that greenish line in the booster picture if that is copper need to change to steel brake line.
