74, was sitting for years, fair amount of rust on fittings, etc.

I replaced the master cylinder, rear shoes, drums and wheel cylinder, and the front rotors, calipers and pads - in other words, everything but the booster and the lines themselves.

And now I can't get the 3 of the brakes to bleed. Only the right front bleeds. Nothing but air coming from the LF, RR and LR.

I did bench bleed the master cylinder - no bubbles, and I get fluid seeping out when I crack the lines to the master cylinder. I also get the little geyser from each side when I push the brake pedal down with the top off the master cylinder.

I have tried both the having someone push the brake pedal method as well as trying a vacuum bleeder.

And nothing. Probably a hundred or so cycles on each of the three wheels. And no signs of fluid leaking from where it's not supposed to be.

Suggestions?

 

Whenever I bleed a system that's been opened, I gravity feed the lines first. Remove the master cylinder cover, open the right rear bleeder, and wait for fluid to start running out. Close that bleeder, and do the same for the left rear, right front, and left front in that order. Don't let the level in the master get too low. Then follow up with the brake pedal bleed method.

 

As Senior suggests, open bleeder and let it gravity bleed.
This will show you if hard line/hose is at fault.
I would suspect a hose as you say they were not replaced.
There is a date on hose, if you can read it, of when made, aka, 4Q74 = fourth qtr of 1974
