Abstract
A remote braking apparatus has a vacuum conduit network that operably connects a vacuum source to both the power boost of the towed-vehicle and a pair of solenoid valves. A vacuum cylinder receives vacuum from the solenoid valves as directed by an electronic circuit connected to the vehicle's battery. The vacuum actuates the vacuum cylinder causing it to move between a resting position and a braking position. A cable mechanically interconnects the vacuum cylinder and a brake pedal of the towed-vehicle. The cable passes through a cable shield tube that is anchored to both the vacuum cylinder and the firewall of the vehicle, thereby directing the movement of the vacuum cylinder to the brake pedal, allowing the vacuum cylinder to control the movement of the brake pedal. In response to a signal from the electronic circuit, the solenoid valves direct vacuum into the vacuum cylinder, causing it to move from the resting position to the braking position, pulling the brake pedal and applying the brakes of the towed-vehicle.
