Full description of the product (H1: FREELINE BRAKE DISC / Birel Art - Usage Front Kz & Rear Mini 60cc)

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.

Technical characteristics:

• Range: Freeline of origin (factory Birel Art)

• Material: Special high friction steel with high thermal conductivity

• Applications: Front brake (adult kz chassis) / rear brake (mini chassis / cadet)

• Compatibility Brands: Birel Art, CL Kart (Charles Leclerc), Ricciardo Kart, Kubica, LGK

• Performance: Maximum mechanical resistance to thermal deformation under a strong load

- 3. Tip in Michel (the corner of the expert)

* "Hi late braking artists! This brake disc, it's a real chameleon: we find it at the front kz to stop the monster at 150 km / h, or at the back on the small bolide of minots in mini 60. In both cases, He eats sacred friction !

My unmissable trick for editing: be super vigilant on the lateral game (the floating) of your disc and on the choice of platelets. If you use it at the front on a KZ, make sure the flotation bushings are not seized by burning platelet dust. The disk must be able to move very slightly on its hub to center itself between the pads during trapper braking.

As fitted, clean it from the bottom with an excellent brake degreaser to remove the factory storage fat film. If you climb a fat disc with new pads, you will glash your pads in two turns and kart will no longer brake at all. And for break-in: Go gradually on the first 3 or 4 tracks of track to let the steel get used to the calories! "*

❓ 5. FAQ SEO (Frequently Asked Questions)

Q: Is this disk compatible with the rear brake of a kart kz or Rotax Max senior ?

A: Not. For the rear brake of adult categories (Kz, Rotax, X30, OK), the disc is much larger and thick to dissipate the huge kinetic energy of the rear train. This model is a "small brake", intended only at the front of the kz or at the back of the mini 60cc.

Q: Is it coming complete with the hub / aluminum disk drive ?

A: Not. This product includes the raw steel disk alone, according to the wear parts of the FREELINE catalog. The disk hub of 30 mm, 40 mm or the front KZ hub are sold separately if your original piece is damaged.

Q: How do you know if my brake disc is to be replaced ?

A: You must replace your disk if you notice a visual veil by rotating the wheel to white, if the thickness of the disc is passed below the manufacturer's wear limit, or if you notice micro-surfaces (thermal cracks) due to a Overheating extreme on the track.
