Hello and welcome to JustAnswer!

Outside of ABS activating and the pedal dropping at the end of a stop, if the pedal is going to the floor then you have a hydraulic issue. There has to be an issue with the master cylinder, ABS hydraulic control unit, or air in the system.

Did the problem start on it's own or did it start after a repair?
