An auxiliary braking device for use in a towed vehicle has an actuator with a moving element that connects via a cable or the like to a brake pedal arm of the towed vehicle. A pulley or similar redirection device is located in the space behind the brake pedal arm with the cable being routed from the actuator to the brake pedal arm via the pulley ensuring that the line of pull on the brake pedal arm is in the direction of the brake pedal's normal movement. The actuator may be a pneumatic actuator that is controlled by pressurized air from an air compressor of a controller. 1. An auxiliary braking device for use in a towed vehicle , the towed vehicle including brakes , a driver cockpit , a brake pedal arm in the driver cockpit for applying the brakes , the brake pedal arm having a non-braking position in which the brakes of the towed vehicle are not applied and a braking position in which the brakes of the towing vehicle are applied , the auxiliary braking device comprising:(A) an actuator comprising a fixed element and a moving element, the moving element configured to move relative to the fixed element;(B) a controller that causes actuation by the actuator;(C) a first attachment that attaches at a brake pedal arm of the towed vehicle;(D) a second attachment that attaches to the towed vehicle at a position behind the brake pedal arm as viewed from the driver cockpit of the towed vehicle toward the brake pedal arm;(E) a connection between the first attachment and the second attachment;(F) wherein the moving element operatively connects to the first attachment; and(G) wherein actuation of the actuator by the controller causes the moving element of the actuator to pull the first attachment toward the second attachment, thereby moving the brake pedal from the non-braking position to the braking position.2. The auxiliary braking device of wherein the connection comprises a connection line claim 1 , wherein the moving element operatively connects to the first attachment ...
