For the development of the new Mini AP06 brake system, Parolin Racing Kart made use of the experienced gained in the homologation of the AP06 model dedicated to the single-speed and shifter categories. The brake caliper, in fact, derives directly from the front version of the KZ system. The main feature of the system is the braking modulation offered to the drivers, an important element when the kart needs immediate braking while maintaining controlled driving when cornering. Cornering speed is a prerogative of the MINI category, where engines are equipped with lower horsepower and smoothness is essential to achieve a great overall performance.

The new caliper which, as said, is derived directly from the front of the brake system for the AP06 shifter categories, it has significantly increased its rigidity qualities compared to the previous version which consisted of two assembled half-shells. The 2020 model, in fact, is CNC machined from a solidblock of material, accurate to one hundredth of a millimeter. Inside it, two 27 mm magnetic pistons control the pads braking strength on the disc. The increase in rigidity is not the only objective achieved by Parolin’s technicians as, thanks to a very pronounced tapering, the AP06 Mini caliper offers better cooling and, above all, a decrease in weight. Another advantage compared to the previous AP-Race model (CSAI homologation) is lower maintenance due to the absence of the half-shells fastening screws and the sealing O-rings. The complete redesign of the oil channels inside the caliper has also facilitated the bleeding of the brake which, being a monobloc caliper, is now only conducted once.

An important innovation compared to the Mini AP-Race model (CSAI homologation) is the caliper’s attachment which now features a radial version instead of the previous axial attachment model. This modification has made it possible to limit the torsion during braking, thus increasing the overall performance of the system. The brake disc is floating and self-ventilated, it also has a diameter of 150 mm with holes on the surface for greater heat dissipation capacity during braking.
