Unless something is putting voltage on the brake output circuit of the trailer wiring the brakes of the trailer wouldn't be activated. So if your trailer wasn't plugged into a tow vehicle the trailer's brakes should not be activated unless the off-chance the breakaway system's pin has been pulled.

I attached an FAQ on breakaway systems for you to check out as well as an FAQ on brake controllers that you may find helpful.
