Question:

Did the trailer brakes lock up when you disconnect from the truck? I put chocks but still seems like trailer wheel are free to roll.?

Trailer brakes do not lock up when they are disconnected from the tow vehicle. They basically are free rolling until a brake controller puts amperage on their circuit which applies the braking mechanisms. Wheel chocks like what you mentioned are what's needed to keep the trailer from rolling.
