BGG,

Since this is coming from a know-nuthin Texican.........

If it was me, and I wanted to put my trust in it, I'd pull the wheels, tires and hubs, check to see whether the spindles are good, and whether the bearings need packing I'd check the brake pads and drums. Most likely you'll only have brakes on one axle.

From my experience, electrical devices work best when there is a circuit. If you have an meter you can check for continuity and a circuit.

I'd bet you could take and but spliced some leads with aligator clips to your brake wires and attach to a battery. If you've a circuit, the brakes should actuate.

Best
