The FREELINE BRAKE CUP (dimensions 25 x 30 x 2 mm) is a high precision replacement hydraulic component of origin manufacturer (Original Freeline / Birel Art). It is designed to ensure absolute internal sealing and pressurizing the circuit at the cylinder master piston on the group's competition chassis Birel Art.

This cup (or specific lip seal) displays an inside diameter of 25 mman outside diameter of 30 mm and a thickness / height of 2 mm. Its technical profile is specially molded to evade under the pressure of the brake fluid, ensuring that no internal leakage occurs when the driver crushes the pedal. Made in a high-end elastomer resistant to chemical aggressions of competitive fluids, it maintains a reactivity of instantaneous and constant pedal, handle after handle.

This High performance treated steel brake disc is a piece of origin manufacturer (Original Freeline / Birel Art). It is a widely known multi-purpose mechanic technique, ensuring two separate functions according to the architecture of your chassis:

1. At the front on KAZ KARTS / KZ2 (gearbox): It settles on specific front hubs to brake on the management train. Its compactness ("small brake" system) allows you to perfectly accommodate the stirrup system in the restricted space of the rim above all by guaranteeing an immediate biting.

2. In the back on the mini karts 60cc / minimal / cadet / micro: It acts as a main brake disc on the back tree for categories of young drivers. Its lightness limits the inertia on the rear axle of 30 mm or 40 mm, optimizing the 12 -CC engine reminders while offering a perfectly messy power for children.

Machined in high quality foundry steel, this disc undergoes rigorous heat treatment allowing it to withstand high temperature mounted without veiling. Its ventilations or factory grooves make it possible to effectively dissipate calories and continuously clean the brake pad surface.
