ABSTRACT:
An anti-theft hydraulic brake device is provided and consists of a valve placed in hydraulic fluid conduit going from a master cylinder to wheel brake cylinders that will keep the brakes locked when the valve is activated from the dashboard after the brake pedal is released. In a modification the valve can be selectively operated from the key operated ignition switch as an additional safety factor.
