I'm not sure what was wrong. But blowing out all the lines and junctions as well as the proportioning valve fixed it.
Now the only issue is a small one. The pedal play is almost 1". I've got to get my fat ass back under the dash and re adjust that brake pedal. I can stop now. The pedal travel is just too long.
How much free play should there be? I'm thinking 1/4"? Whatis that? 8mm?
