Hi there,

You may have a faulty master cylinder that is by-passing fluid internally. This will case the pedal to drop and there is no fluid loss. You can normally pick this by pumping up the pedal and holding hard pressure , the pedal will normally sty up but if you back off the pressure and hold constant light pressure the pedal slowly drops away.
