was gonna try the gravity feed one, but thought I'd do it one better and put some pressure (motive bleeder) through it, and that was my last resort. Now I'm stuck.
Car does not have ABS.

another guess
any device in the lines may be trapping air especially if using psi or pedal pump bleeding.
if my problem I'd start with pulling brake pads. I'd file the leading edge leading into the caliper so I could extend the pistons out from the calipers far enough so I'd have to force the pads into the caliper. Tight enough so that I'd need a rubber/whatever hammer to get them in.
If still a problem I'd start bleeding before and then after any device in the system.
I'd only do gravity bleeding at this point to prevent any unintended consequences.
I assume the pedal can't be pumped into a hard pedal, right ?
