Tom, If you aren't losing fluid from the system, it is almost certainly a defective/damaged master cylinder. The classic test of a master cylinder involves first "stabbing" the brake pedal (stepping on it hard and fast). This will often cause a worn piston cup to momentarily seal and hold pressure. Then release the pedal and rest your foot lightly on it and slowly push down. A bad master will seep fluid back into the reservoir, and the pedal will sink.
