1995 Le Saber brake problem

Got this 95 Le Saber with this problem, the brake pedal sometimes operates normaly then sometimes it goes almost to the floor before starting to stop
the car. It has AbS and the pads are all good. The fluid level is up. Could not see any fliud leaks by the wheels from under the car. Lately it is getting more often with the low pedal thing. What gives? Anybody else had this problem? Any advice? Good, bad, or ugly, would be appericated. I will check back daily to see if anybody cares. If nobody does thanks anyway, Tom.
