The surge brake has been lubricated and I can feel the brakes come on and then release as I apply tow vehicle braking. Trailer rolls easily when pushing it around by hand. Don't believe the brakes are causing overheating as the hot condition was noted after 3 hours of straight towing at freeway speeds with little or no breaking action, but the fact that both hubs were hotter than normal would seen to eliminate the chance of both bearings failing at the same time. I did notice the hot condition right after a rather steep descent into Susanville, Ca, so maybe the trailer brakes did heat things up during this descent. I'll check it again after some level ground towing.
Thanks for your input, I think we may have just figured it out.
