The REDARC Tow-Pro Liberty is the latest innovation in brake controller technology that features inertia-sensing technology perfect for hauling day to day or towing on highway conditions. Rugged Reliability Meets Everyday Ease-of-UseThis proportional brake controller measures the vehicle braking force and applies the trailer brakes to match, ensuring a smooth braking application and no push or pull on the vehicle when braking.
