Car is frame off restoration. First master cylinder couldn't get fluid to the rear. Replaced it after bench bleeding. Same issue. Replaced proportion valve same issue. All lines rotors cals every part is new....HELP
I just did the brakes on my 68 and had similar issues. I spent the money and bought a Motive power bleeder and now the brakes are perfect. Well worth the money.
Try process of elimination. Break the line loose at the the master, does fluid come out ? If yes then go to next fitting, proportioning valve, does fluid come out, if so then move to a caliper. You have to figure where the fluid is stopping, it's possible there's something in the line blocking fluid.
Look at their website for corvette tips. I use A big c clamp. It works well but I did gravity bleed the right front when I had to replace it a month or so ago. That worked great, for the first time ever.
How does the motive bleeder attach to the master cylinder?
I bought the one with the adapter for the GM master cylinder. It is a bit larger than the MC, but once sealed properly, it worked perfectly. I used the J bolts and the chains and really had no issues with it. I suppose you could use a large C clamp as others have suggested.

I've read that you can make one from a mc cover. Just drill a hole and tap for a barb hose connection and seal it. They average around $15 and the motive bleeders are on amazon for $52
