I don't think you did anything wrong. Actually, the brakes on your vehicle shouldn't lock up. However, if the ABS light is on, they should. Regardless, check the ABS sensors at each wheel. One of the sensors may have come disconnected or one of the wires may be damaged and you just bumped something when you were working on it.
Let me know what you find.
