How many times have you said to yourself: “I can't find the right feeling when braking”. There are several variables to consider in order to solve this problem: the conditions of the track, perhaps too slippery or too rubbery; a too aggressive approach, or on the contrary being too delicate on the brake pedal, or, in relation to Shifter karts, an incorrect distribution of braking between the front and rear axles (but it could be a long list …). All braking systems have different setting modes in order to adjust and refine braking to your liking. However, up to now no system has ever allowed a complete reversal of the operating architecture of the system. Until the present day… Because, with the LKF 13 (Shifter) and LKF 14 (Direct Drive) braking systems, Lenzokart has for the first time marketed devices that have a brake pump with an innovative structure, which combines two types of activation of the pumping element, i.e. for direct traction and compression, via a lever. Two solutions that have a braking method that are quite different from each other. How is it possible? As mentioned, their structure is the fulcrum of everything. In fact, the Italian company has designed a brake master cylinder (single for the system intended for Direct Drive karts and double for the Shifter ones) which can be mounted in two different ways and which allows kart drivers to switch from modulable braking (braking with traction drive) to more aggressive braking (braking with compression drive) in a few quick steps. Both braking systems were CIK-FIA approved in 2022 (to find out how the approval process works in karting, read "Dossier | FIA Approvals: what they are, what they are for, how long they last... the definitive guide!"
): LKF 13, with the number 033-B4-13, is the system configuration for Shifter karts (equipped with double brake master cylinder and front brakes); LFK 14, with the number 033-B2-14, is the system for Direct-Drive karts. In this article we find out how they work and what their main characteristics are.
