problem bleeding back brakes

The valve closed off,did it's job. as the pedal travel was over-pushed. Only push 1/2 way then close bleeder.To re=center- open front bleeder, turn on key, push pedal,watch brake light go off, or feel the click in the pedal. Valve back to center, now will allow fluid to rear/ front again. Don't push pedal past 1/2 way.
