It takes a lot of power to stop a moving trailer, especially when that trailer is hauling a heavy load. On RVs, flatbeds, livestock trailers and many other oversize haulers, manufacturers typically install trailer brakes to assist the tow vehicle in bringing such a massive amount of weight to a halt. But it takes more than a good set of brakes to make quick, efficient stops. It takes precision and the right amount of control. The crown jewel of CURT''s brake control lineup is the TriFlex™. This proportion-based brake control features a compact size, a digital display and the ability to manage up to eight brakes at a time. The feature that sets the TriFlex™ apart from all others is its triple-axis motion-sensing accelerometer. This integrated circuit component allows the TriFlex™ to detect every motion of your vehicle and trailer with exact precision and to then apply the perfect amount of braking power for every situation. The TriFlex™ also automatically adjusts brake output when going up or down a hill and is compatible with anti-lock brakes and cruise control. All CURT brake controls are designed to work with quick plugs so that they can readily plug into your vehicle's original equipment socket. A brake controller should be mounted somewhere on the dash of your vehicle, and we recommend putting it below the steering wheel, either on the right or left side of the steering column. This way the control will not block your view when driving, but it will remain accessible and visible when adjustment is needed.
