The 2nd class lever is demonstrated in drum brake systems. Each of the two brake shoes is connected to a hydraulic cylinder that applies the force to the shoes causing them to expand outwards to contact the rotating drum. The contact surface of the shoe is the load, the fulcrum is the pivot pin on the backing plate opposite the wheel cylinder. The foot pedal, itself, also demonstrates the 2nd class lever. The force is applied to the foot pad while the anchor point (fulcrum) is at the opposite end. Between the applied force and the fulcrum you will find the rod that transmits the force to the master cylinder's piston.
