Having a supplemental tow brake installed helps prolong the brake life of the coach, if the coach brakes are doing all of the work to stop the combined vehicles, they brakes will wear prematurely. The coach will brake more easily and the stopping distance will not increase due to the increased weight of the towed vehicle. The Patriot from Blue Ox gives you the comfort needed for when you’re braking your tow vehicle. Not only is it convenient and easy to store, but it also proportionally applies the brakes while you’re slowing down to a stop, instead of suddenly jolting your tow vehicle causing costly damage to your brakes.
