ABSTRACT:
A vehicle anti-theft device that blocks and unblocks the flow of hydraulic fluid between a vehicle's master brake cylinder and wheel brake cylinder. When the invention is in a fluid blocking position, it locks the brakes and prevents movement of the vehicle on its wheels. Conversely, when the invention is in the nonblocking position, the brakes are unlocked and the wheels turn freely as in normal operation. The anti-theft device can be deactivated within the vehicle or by remote control.
