Most people do too much pedal pumping when they're bleeding brakes. One or two gentle pushes on the pedal should be plenty, then hold the pedal down until the fluid stops flowing, and close the bleeder. Pumping the pedal too much emulsifies the air into the fluid and it takes hours for it to form bubbles big enough to bleed out again.
