Please provide whether single or tandem trailer and the type of bearings you have. If your trailer is wired for a 5 wire plug, you may want to splice in 12 volts of power to the blue wire which should be the solenoid to interrupt the brakes for backing up. This should allow you to tow and only stop the trailer with the tow vehicle brakes and should eliminate the heat coming from dragging brakes, if the wheel spins freely before you start.
