92 Lesabre break pedal sinks to the floor

OK gang...here's one for you. Just sitting at a stop sign, my break pedal just sank slowly to the floor. I thought it might have been due to air in the break line from a leaky rear brake cylinder. I changed it and blead the breaks. The break is a little firmer but still sinks to the floor.

Master Cylinder....??? or some other part belonging to the ABS system?

Anyone have any suggestions?

A bad Master Cylinder will do that - slowly sink with no leaks anywhere. Usually, you lose 1/2 your brake system and the pedal almost hits the floor. I believe the ABS system just transfers braking force to the other wheels when a wheel skids.
