Stability system disabled

What is your question?

The stability system disabled came on after my truck came to a complete stop and now it doesn't drive forward in any gear, the brakes go all the way to the floor, and the vehicle will only drive in reverse. Even after replacing the calipers, the brakes, and the rotors, why is it still not driving?

How long has your 2003 GMC Yukon XL 1500 had this problem?

This happened thanksgiving night
