Abstract: A vehicle anti-theft device which is mounted on or in the instrument panel of said vehicle and which is connected into the brake fluid line that extends from the master cylinder to the brake wheel cylinders. By closing the valve while the vehicle brake pedal is depressed, fluid under pressure is trapped between the anti-theft device and the wheel brake cylinders, locking the wheels. The closed valve prevents reverse flow of the pressurized braking fluid until an authorized person in possession of the proper dial symbol to reference mark combination once again manually reorientates the set of dials that are attached to a plurality of cylinder valve port tubes and one spool that are rotated in proper sequence to bring all the tube ports in alignment with the casing ports.
