摘要： An apparatus for actuating a hydraulic brake has a housing with a cavity communicating with an input and an output for hydraulic fluid. The housing is adapted to be positioned between a master cylinder and a wheel cylinder in a vehicle hydraulic brake system. The cavity receives a valve apparatus in the form of a sleeve and a piston for opening and closing to control a flow of hydraulic fluid. The cavity also receives a seat, and the seat movably receives a transmission assembly that communicates with the valve apparatus. A driving system drives the transmission assembly to actuate the valve apparatus. A control circuit receives a code from a user to activate the driving system. A measuring device determines a duration of activation of the driving system. The valve is open during normal operation of the vehicle. To lock the brakes for security, the code is entered and if correct, the valve closes, thereby acting as a check valve. Hydraulic medium is forced through the valve to the wheel cylinders. The hydraulic medium is prevented from flowing back through the valve, thereby locking the brakes.
