Same thing happened to my brothers car. The master took a crap and caused the same reaction. Replace both it's very easy to do. Also check the release spring on the clutch pedal to make sure it's not caught in the way or anything and that it's installed properly. You have to bleed the system very throughly it took me probably 20 times of pumping the pedal to get the air out... and make sure when you install the master you bench bleed it first.
