ABSTRACT:
A vehicle anti-theft device which upon activation, maintains the braking function of the braking fluid by preventing reverse flow thereof from the wheel cylinder back to the master cylinder once the brake pedal of the vehicle has been pushed. Improvements over prior art are; no brake fluid is trapped between the wheel cylinder and the one-way valve upon activation of the device until after the brake pedal of the vehicle has been pushed; no indication exists either with the switching device or with the mechanism itself, to indicate to other than to an authorized user, the state in which the valve is currently set.
