Wheel hub for a vehicle and braking system therefor

19) A braking system for a vehicle, the braking system including:

• a) a wheel hub, including:
• i) a wheel axle defining an axis of rotation for the wheel;
• ii) a hub body rotatably coupled to the axle for rotation about the axis of rotation, the hub body defining an internal cavity;
• iii) at least one first annular plate disposed within the internal cavity about the axle, the at least one first annular plate rotatably fixed with respect to the hub body so as to rotate therewith about the axis of rotation;
• iv) at least one second annular plate disposed within the internal cavity about the axle and adjacent to the at least one first annular plate, the at least one second annular plate rotatably fixed with respect to the axle, and at least one of the first and second annular plates being slidably movable within at least part of the internal cavity;
• and,
• v) an actuator disposed within the internal cavity and configured in use, to cause an axial load to be applied to the slidably movable plate to thereby cause the at least one first and second annular plates to frictionally engage thereby applying a braking load between the hub body and wheel axle so as to brake the wheel of the vehicle;
• and,
• b) a brake lever coupled to the actuator and operable by a user to selectively cause the actuator to apply the axial load to the slidably movable plate so as to brake the wheel of the vehicle.
