Abstract
A vehicular anti-theft system with brake line valve including a valve mechanism connected to the plurality of brake lines between a master cylinder and the associated brakes of a vehicle. The valve mechanism includes a housing with a solenoidal valve therein associated with the brake lines. The solenoidal valve has a first orientation with the solenoidal valve preventing control of the brakes by the master cylinder. The solenoidal valve further has a second orientation with the solenoidal valve thereby allowing control of the brakes by the master cylinder. The solenoidal valve includes a relay adapted to transfer between the first orientation upon and the second orientation. The solenoidal valve is adapted remain in a present orientation thereof without consuming power. Lastly, control circuitry is connected to the valve mechanism.
