Are you explaining this correctly? Sounds like you pushed the pedal down just once. The brakes should bleed thru from gravity alone, without even stroking the pedal. It helps to use vacuum at the bleeders (grease threads to seal air out). If still nothing, start disconnecting the tubing upstream until you get fluid. I once got nothing from a front caliper (~1993), so had a helper push the pedal hard with both feet. A big clot of rust junk blew out the bleeder hole. I have used DOT 5 silicone fluid in all my non-ABS cars since, and no more rust.
