d) Wheel Brake Cylinder
The last link in the braking circuit of a service brake system is the wheel brake cylinder which converts the hydraulic brake pressure into a clamping force. At a prescribed service pressure, the cross-sectional area of this simple hydraulic component decides the magnitude of the clamping force and thus the brake force. The cross-sectional area of the brake piston is limited by the packaging space within the brake drum or on the wheel.
