ABSTRACT:
A remotely activated electro mechanical device is mounted in the dual chamber brake system of a vehicle or trailer. The device includes a solenoid valve and a receiver decoder which controls the valve in response to a coded signal ideally available only to law enforcement to vent pressure in the emergency chamber of a dual chamber brake system to automatically apply the brakes thereby bringing a moving vehicle to a stop. The device is also responsive to a second, different coded signal, available only to authorized users to vent pressure in the emergency chamber and to lock the brakes by preventing pressurized air from being supplied to the dual chamber brake system of a stopped or parked vehicle. The device is also responsive to coded signals which reverse the above-noted actions.
