old style electric brakes are rather simple, basically, a magnet activated by the amount of electricity applied through a rheostat type brake controller. I bet if you pull the drums and clean the contact surfaces, the brakes will work. You will need to insure the brake shoes are free to move when activated. I have had electric brakes on many trailers, including a 9800. lb tandem dump trailer and they work perfectly. The only thing you must do is regulate the dash mounted brake control for the weight of the load, too much electricity and you will slide the tires etc. Good luck.
