The principle of operation is as simple as it is effective. Inside the pump there is a shaft (whose diameter can be varied if necessary), which is directly connected to the brake pedal by means of a rod. The pumping element is mounted on the shaft, a sort of ring whose function is pushing the oil into the system circuit and directing it to the caliper. Once the brake is pressed, the flow of the oil is immediate, given the absence of play and friction present in the pumps with leverage. The intensity of the braking effect is directly related to the size of the shaft you decide to mount. In fact, the volume of oil that the flange pushes is obtained from the difference between the total volume of the internal chamber of the brake master cylinder and its volume. With the same flange, therefore, if the diameter of the rod is increased, the volume of oil to be moved is reduced and the pressure generated by the system increases. In other words, by applying the same force to the brake pedal, a rod with a larger diameter allows for greater braking power.
The first version of the Italfreno system made its debut in the 2017 KZ World Championship in Germany, in which it contributed to the achievement of third place for the Croc Promotion team, with driver Ben Hanley.
The pump and caliper, still on an experimental basis, had a rougher style and more angular shapes than those that were actually approved.
The Italfreno master cylinder kit. In addition to the [1] pump body and [2] to the pumping assembly, we can see the [3] bracket for attachment to the chassis and the [4] optional shafts of different diameters.
The ergal shaft is the central point of the system designed by Emme Racing. Its operation is inspired by that of the formula classes.
The rubber pad and the different position of the wedges allow you to adjust the free movement of the shaft and therefore of the brake pedal.
Above, the displacement pump setup positioned on the shaft to offer a reduced idle stroke. Below, vice versa, the setup that allows giving a greater stroke.
In the video, the activities required to reverse the thicknesses on the shaft that allow you to affect the responsiveness of the braking system to pedal pressure. Below, the elements that make up the rod/pumping assembly.
The cap that closes the pump has a rubber anti-dust seal inside.
The kit that is supplied for mounting the external oil tank with respect to the brake pump.
The configuration with the tank mounted directly on the master cylinder.
The configuration with the tank mounted externally with an extension tube.

In the above interactive animation you can see the operation of the Italfreno pump. In the first part of the animation it is possible to see how an internal shaft with a smaller diameter exerts an X force. In the second part of the animation, however, it is shown how, as the diameter of the stem increases, the pressure generated in the system with the same force exerted on the pedal.
