Developed by the Praga Kart, Formula K and OK1 Racing Teams in the most important competitions around the world, the IPK braking system guarantees the high standards of quality both with regard to performance and reliability. The construction technique reflects the philosophy of all IPK accessories: machined from solid and finished in every detail.
The master cylinder, used for all classes, is made of aluminium, machined from solid and produced using CNC machinery. Inside the cylinder there is a 19 mm diameter piston. Located above the cylinder is a “stroke recovery” bowl, whose task is to guarantee the same stroke of the brake pedal even when brake pads are worn. Externally, the master cylinder is titanium-gold anodised, like the other accessories on the chassis; the oil in the system is Xeramic brake fluid dot 5.1.

The soul of a braking system is the rear brake caliper, which equips both shifter and non-shifter karts. Several years of development have led to IPK specialists selecting the radial type attachment. This solution enables the elimination of the flexing during operation that occurred with a lateral attachment. The caliper, machined from solid, is an aluminium monoblock produced using CNC machinery that guarantee uniformity and centesimal precision. The braking force of the brake pads towards the disc is exerted by two 28 mm diameter pistons.
