There's much in the archives on bleeding brakes but nothing that addresses my specific question.

Trying to bleed the brakes on a '51 3100. I've completely overhauled the master cylinder and rear wheels (honed the MC and put a kit in it. New shoes, drums, 1 new WC, 1 WC kit on rear wheels). I have a shop manual and have followed the steps for adjusting the brakes following a rebuild.

When I push on the brake pedal, I can pump it a hundred times and I get no resistance. I have the left rear bleeder screw opened into a hose which goes into a jar with fluid in it, but nothing is going through the hose.

Absolutely no pressure or resistance in the MC makes me wonder if I've over-honed it, but the new rubber cups seem to fit really snugly in the cylinder.

If I take the filler cap off the MC and gently pump the pedal, I can see a little turbulence in the fluid, meaning something is moving down there. The cap has a vent hole in it, so I'm having to hold my finger over it when pumping.

Does anybody have any idea what I can troubleshoot next?
