Patented system “senses” the amount of braking effort required and provides for a smooth, safe stop. Wireless in-cab controller plugs into tow vehicle’s cigarette lighter, needs no special wiring to control trailer mounted actuator. Ideal for rental fleets or shared trailers…need to change tow vehicles? Just move the in-cab controller from tow vehicle to tow vehicle and plug into cigarette lighter. Vastly superior to surge brakes…eliminates feel of being pushed by trailer and problems with backing a trailer uphill. Improves braking on trailers hauling boats, RV/Campers, horse/livestock, cars, construction and farm equipment and many others. Meets all DOT regulations and complies with CFR-393 federal braking requirements…surge brakes are illegal in many states and provinces.
