Did it act like that before?
you really don't need to bleed them for rotors and pads. chances are you just got air in the line. Bleed them again. Put a hose from the valve nipple to a bottle with brake fluid in it. Pump till no air comes out. Close bleeder valve. If it was like that before and you try bleeding a few more times and it still won't work then you probably have master cylinder trouble.
