I have actually had the one bolt that holds a surge brake coupler together break due to dolly wheels getting stopped by debris on interstate highway. I'm glad my break away cables held. One advantage to electric brakes is more than 1 bolt and no sliding connection in the coupler like surge brakes.

Actually the Master Tow dolly has a slot in the surge coupler to stick in a 5/16" common screwdriver which locks out the surge brakes. if you plan on backing up.
