Brake pedal retaining vehicular anti-theft brake locking mechanism

Claim 1

A brake locking mechanism for use in a vehicle having a vehicle ignition switch and a vehicular brake system having a brake actuating push rod reciprocable by a pedal operable lever into a brake applying position, comprising: (a) an elongated linking member having first and second ends, said first end securely affixed to the pedal operable lever; (b) a piston slideable in a cylinder and defining a fluid chamber therewith, said piston operatively connected to said second end of said linking member; (c) a fluid pump for introducing a pressurized fluid through a fluid line into said chamber so that said piston is displaced in said cylinder to pull said linking member to position the pedal operable lever into the vehicle brake applying position; (d) a three-way valve positioned in said line operable between first and second positions, wherein said first valve position vents said chamber and blocks fluid introduction into said chamber, wherein said second valve position closes a vent and permits fluid communication between said pump and said chamber; (e) a remote switch for actuating said pump; (f) a relay operatively associated with the vehicle ignition switch to prevent actuating said pump unless the vehicle ignition switch is in an "off" position; (g) a pressure switch in fluid communication with said fluid line associated with said pump to said chamber for deactivating said pump when pressure in said line is above a predetermined set point; (h) means for remotely repositioning said three-way valve between said first and second positions.
