ABSTRACT:
A hydraulic wheel brake device is provided for connection between the master cylinder and the wheel brake cylinders in the brake fluid line. The device includes a lock housing connected to a hydraulic cylinder wherein the hydraulic cylinder includes a fluid chamber having an inlet and outlet in fluid communication with the chamber. A valve seat is located over the inlet in the fluid chamber and a spring is disposed in the chamber having a steel ball held therein. A lock and rotary cam mechanism are located within the lock housing wherein rotation of the lock rotates the cam mechanism thrusting a rod connected between the rotary cam mechanism and the spring. The rod forces the spring to compress which seats the ball against the valve seat restricting fluid flow to the brakes thereby locking the fluid brake system.
