Alright, I think this one is licked for now. I will say, it's not perfect, but its just as good as it was. What I mean by that is when I took some vice grips (padded jaws with a shop towel) and gently squeezed the soft line from the frame to the rear axle, the brakes were fantastic, completely firm pedal, even with the engine on- So I know the issue is in the rear circuit, and my bet is that its air trapped in the cylinders. I once again cranked down the wheel cylinders as tight as I could make them, re-bled, and its better than it was a few days back. I'll drive around like this for a few more days and try the method again, see if I can improve it further.
I took one of the old cylinders out of the trash and disassembled it, its pretty simple as for the internals: on either side a piston, rubber gasket, and a plastic piece that centers the spring, with the spring in the middle. I was considering how, once brakes were disassembled,I could remove the shoes, the cylinder boots, and then fill up the cylinders. This would require removing the "top" half of the assembly on either side. Sure you could fill up fluid (assuming you could get the rubber gasket out without tearing it, but even if you topped it off to the brim, the rubber gasket would trap air when you reinstalled it. Has anyone else done this? I didnt want to disassemble the brakes all over again, so I didnt proceed down this path. But I assume this is the last place air could be trapped.
Anyhow, thanks to all of you for the help. Its just in the nick of time, but now I'm able to join the all 40-series run with my local chapter tomorrow. Super excited about that!
