This front brake caliper support for KZ (gearbox) category is a high precision mechanical part of origin manufacturer (Original Birel Art). It is specifically developed to adapt to the latest generation of rockets appeared on the 2025 range.
CNC machined in a block of aeronautical quality metal with a black anodized finish, this support ensures the critical and rigid connection between your front rocket and the brake caliper. In Kz, the front braking system undergoes colossal pressures. This support is dimensioned to eliminate any mechanical twist during violent braking, ensuring a perfect alignment of the pads on the disc and an ultra-precise feeling at the pedal.
As visible on the official image support-Caliper-de-brake-kz-2025-birelart.jpg, the kit comes complete with its safety fixing accessories:
1 front brake brake holder (Black anodized, geometry 2025).
2 fixing screws high threaded head resistance.
2 middle nuts specific coppery for resisting high temperatures without seizure.
2 circlips / security clips steel to lock the hardware.
This support is mounted exclusively on the 2025 range rockets manufactured by the factory Birel Art:
Birel ART (S16 / S18 ...)
CL Kart (Charles Leclerc)
Ricciardo Kart
LGK
* "Hi have big braking in kz! The caliper holder is the backbone of your brake before. If this support takes from the game or is poorly mounted, your stirrup works through, the pads wear out, and you lose all the power at the end from the straight line.
My trick of old mechanics: never be struggling on safety with brakes. As can be seen on the image
support-Caliper-de-brake-kz-2025-birelart.jpg, The factory provides coppers and small safety circlips. It's done for a good reason! The heat of the discs before rises very quickly and is transmitted to the support. The copbatures prevents the thread with calories.When mounting on your 2025 rockets, tighten to the couple recommended with a torque wrench, and imperatively put the two small metal safety clips in the planned grooves. If you forget these clips, with the vibrations of the KZ motor at 15,000 turns, the hardware can loosen. A clean brake shot after each round and you will ride the quiet spirit! "*
Place the kart on trolley and remove the front wheel as well as the 40 mm hub. Unscrew the old caliper holder connected to the 2025 rocket.
Clean the mounting area on the rocket using brake cleaner. Make sure there is no debris or impact trace so that the new black aluminum support plate perfectly flat.
Present the new support (reference support-Caliper-de-brake-kz-2025-birelart.jpg) on the rocket. Insert the high resistance screws from the back and secure the bracket with the copies supplied.
Tighten the whole firmly. Apply the tip to Michel by imperatively installing the two steel locking circlips at the end of the screw axes. Reassemble the hub and rim, then perform a few pressures on the brake pedal to validate the bite and alignment.
Q: Does this support adapt on the models Birel Art from previous years (2023, 2024 ...) ?
A: Not. Factory Birel Art A modified the anchoring and geometry of its rockets on the range 2025. This support was specifically machined to match this new technical implantation. For old chassis, please refer to the preceding generation media available on our site.
Q: Can this support be used for the left side and the right side ?
A: No, front brake brake brackets are asymmetrical directional parts due to the orientation of the stirrup relative to the rocket. Be sure to select the side (left or right) you need when ordering.
Q: Why do the nuts supplied have a coppery appearance ?
A: The copper coating on the crankcase and braking karting is used for its exceptional anti-greene properties facing very high temperatures. It avoids that the nut definitely locks on the stud due to the intense heat generated by the brake discs in Kz.
