1st off never bleed the brakes on a running vehicle , 2nd you have to bench bleed the master cylinder completely , otherwise it will turn into an aggravating job.
Try bleeding the brakes with the engine running there may still be some air in the system. make sure the master cylinder doesn`t run out of brake fluid.
replaced booster 2nd new one , 1st was bad out of box have great brakes ,brakes blead went awesome first time i did them , i hade a feeling something was wird that pedal went to floor .
