I just rebuilt the rear calipers, new seals, pistons, already ss sleeved.
the first one bled out just fine, and as expected.
the second one doesn't bleed at all!!!
plugged brake line?
does this happen? rare? common?
I can't get any fluid to flow from either of the bleeder screws. what to try next? I figured I should query the collective wisdom of the forum before I
Thanks for any wise words.

Check fluid is getting to the caliper by loosening the brake line and touch the brake pedal, check for seepage. if fluid is getting to the caliper the inlet port may be blocked with debris from the rebuild. If no fluid then the blockage is in the lines from the distribution block.
Rubber lines can swell internally and block the hose completely. If it is the rubber, hose replace both.

Good idea, that should isolate the problem quickly.
I was leery of the rubber hoses, since they are who-knows-how old, but figured I'd better stop somewhere with the "while I'm here" thought. I'll check it out tonight and hope for something easy.

I'd bet it's the rubber hose. I had that problem twice(diff. vettes) with the front hoses.

Both front hoses on my 74 were blocked. Not the steel line, fluid flowed just fine down to the rubber then it stopped. Replace both when replacing the calipers and all is well.

Flex lines are a bad place to stop thinking about replacing.
Get the Russel set in stainless braid ... available at ZIP.
They are very nice and should hold up better than an
aftermarket rubber replacement. Yeah - $70 ain't cheap,
but it is a decent price for insurance on your life.
If you just need fronts or rears then go rubber at $12.50 each.

Had it happen to me too. Brake line would allow fluid one-way only. Unfortunately for me it was one-way into the caliper causing the brake on that wheel to overheat. After just 2 miles I had smoke coming out of the wheel well everywhere and the rotor was glowing. Turned out the rubber line was collapsed and just a small piece of rubber had pulled away from the inner lining.

Certainly is a good chance you have a failed brake hose, but you could also have a proportioning valve that is closing off the rear system. Could have shifted closed after the first caliper was bled.

Thanks for the wisdom...I just ordered a set of the stainless from ZIP. Pricey, but not that much more than the rubber set. Old rubber makes me nervous, I should have just done this from the start. While I'm waiting for these to ship I'll do some poking around to see where the clog may be.

Can you elaborate on this a bit more? Mainly just more details on what to do to fix it.
