Neither of these is possible with surge brkaes. what are you talking about? "dialing" it isnt necessary at all on surge brakes because you only get exactly what you need anyway. premature lock up isnt a concern with surge brakes because the vehicle will provide less braking pressure anyway as it will also have less traction on gravel roads or wet pavement. this is the beauty of surge brakes, and this is why rental trailers are equipped with them....theyre idiot proof and require no thinking or adjustment. i could have made electric brakes work just fine but i also wanted a trailer that my wife could just hook up to and run, without have to try to teach her how to get close with an electric adjustment. besides, with the nature of my work the load would change many times throughout the day and the self adjustment of the surge was the way to go. that said, the expense involved makes surge brakes impractical for most and anything that can be pulled by a swb jeep would probably do just fine with electrics. -- Nathan W.
