The new MKB.V2 brake system

The new MKB.V2 brake system

With the new CIF-FIA international regulation which came into effect since the current homologation cycle, the MINI has asserted itself as one of the most competitive and demanding categories on the international karting circuit.

IPKarting has enthusiastically accepted the challenge posed by the new standards, along with the new Praga Monster EVO 3 chassis, the equally new MKB.V2 brake system. This braking system is the result of the persistent and the dedicated work of the Research & Development team which, thanks to the use of the latest technologies in the design and production phase, combined with great care in the choice of materials, guarantees a quality product that is at the top of the market.

Let us review the details.


The caliper chosen for the new MINI system originates directly from the front caliper installed on KZ karts. The MKB.V2 features a 4-piston caliper (where each piston has a diameter of 19 mm) equipped with special grooves to improve heat dissipation.
The overall objective behind the project was to minimize the risk of the wheels locking up and provide a more smooth and controlled braking.
The caliper follows all the fundamental principles of the philosophy which guides the manufacturing of IPKarting accessories. Meticulously machined from a solid block of metal by using numerically controlled machines to minimize the overall weight, the caliper benefits from the utmost attention to every functional and aesthetic detail.
The assembly is done by the means of a radial attachment, a solution that offers greater rigidity and is adopted on karts dedicated to the more experienced drivers as well.


The MKB.V2 system installed on the Praga Monster EVO 3 features a floating and self-ventilated brake disc, 149 mm in diameter and 11 mm thick. IPKarting placed great attention both on improving the cooling system and the cleaning of the pads by providing a careful drilling and milling of its surface. The result is a constant friction between disc and pad, which is maintained even after repeated use. Furthermore, the milling ensures greater sturdiness, significantly reducing the risk of cracks or breakage.


IPK Group has always paid particular attention to the master cylinder, a crucial component which transforms the force placed on the pedal into pressure of the pads against the disc. For the MKB.V2 model the company decided to use the same pump installed on the karts in the higher categories. A 19 mm piston operates inside it, while a stroke recovery tank, located above the cylinder, has the task of keeping the brake pedal stroke constant with the wear of the pads. Longevity and performance are ensured by the Xeramic DOT 5.1 brake fluid which boasts an excellent viscosity at all operating temperatures. Like other accessories, the master cylinder is machined with numerically controlled machinery and finished with an anodizing treatment.


Another important attribute of IPK Group has been the wide choice of brake pads, which adapt to the characteristics of any track and the driving style of all drivers. Three different solutions are available for the MKB.V2 model.

SOFT: identified by the color green, it is composed of the softest friction material. Its feature is that of offering powerful braking even with little pressure, at the expense, however, of a quicker wear period.

MEDIUM: red in color, as the name implies, it is mid-way between the SOFT and the HARD versions. This is the pad with which IPK chassis are equipped with as standard. Its adaptability to any condition and driving style is the result of the work carried out with the drivers of the Group’s official racing team.

HARD: identified by the color BLUE, it guarantees a very low wear thanks to the hardness of the friction material. It is suitable for those who prefer a gentle braking or are used to applying a lot of pressure on the brake pedal.
