The Patriot works for your motorhome and tow car by safely bringing it to a smooth stop with proportional braking. No more wires - Monitor all brake functions or manually apply brakes from the comfort of the driver's seat through a wireless remote control. This remote continuously communicates with the braking system. No more power concerns - The built-in battery ensures power is always available to the brake. No more mess - By using an electric cylinder there are no air pumps, storage tanks or hoses; therefore there is no chance for leaking and greatly reduces the power required. All Electric! No Pump, Tank, Or Air Hoses To Leak
