Full description of the product (H1: BRSS brake disc ventilated - Group OTK)

The bSS front brake disc OTK is an original manufacturer braking component (Original OTK Kart Parts), specially developed for front braking systems BSS which equip the group competition chassis OTK (Categories with KZ gearbox and DD2 direct transmission motors).

Made in an exclusive high-carbon steel cast iron alloy at the Italian factory, this disc enjoys an advanced ventilated architecture. Its internal channels are optimized to extract hot air and cool the front train during massive deceleration phases at the end of straight line.

⚠️ ATTENTION AU SENS DE MONTAGE: Due to the specific orientation of internal ventilation blades and direction of rotation, this disc has a right side and a separate left side. Be sure to select the desired side in the options before adding the product to your cart. A disk mounted upside down will reveal its highly reduced cooling capabilities.

Technical characteristics:

• System range: BSS (Manual Front Brake for KZ / DD2)

• Disk Type: Ventilated and thermally optimized

• On the side available: Right or left (choice)

• Material: High performance anti-fading steel cast iron

• Chassis compatibility: Tony Kart, Kosmic Racing Kart, Kart, Redspeed, LN Kart (Lando Norris), Gillard

• Origin: Original certified OTK

👨🔧 3. Tip in Michel (the corner of the expert)

* "Hi trapper braking specialists! The BSS system at the front, that's what allows you to make a difference at the end of the straight line in Kz. As much to say that it heats hard.

My unmissable trick for these discs: do not deceive yourself aside when ordering and editing !

Why is there a right disk and a left disk? It is because of the ventilation channels inside the slice of the disc. They are oriented by propeller. When the kart rolls forward, the rotation effect must act as a turbine to 'suck the fresh air by the center and scroll it outward. If you reverse the right and the left, the air is pushed back, the heat accumulates in the heart of the hub and you risk veiling your discs and cook your rocket bearings in just two sessions.

Another small council of old mechanics: when you mount your new disc on the front hub OTK, clean the reach with the metal brush. Only one small impurity or a grain of sand stuck between the aluminum hub and the disc, and your disc will not rotate. Use from medium net brake on the fixing screws and tighten in a very uniform cross-cross! "*

❓ 5. FAQ SEO (Frequently Asked Questions)

Q: How to visually differentiate the right disk from the left disk to unpacking ?

A: Look at the internal ventilation channels located on the slice of the disc. When the disk is positioned on the kart, the internal fins must be oriented towards the back of the kart by going upwards, so as to evacuate the hot air back when the wheel turns forward. Original packaging OTK also mention the specific reference right or left.

Q: Is this disk compatible with the front brake systems (at the pedal) type BSZ or BSS for ancient generation ?

A: This disc is designed specifically for the front braking system BSS (Manual lever controlling control). For foot control systems (such as the BSZ or MX model), be sure to check the dimensions (diameter and fixing center) because the front hubs and the calipers offsets may vary by year.

Q: Should we change the two discs before at the same time ?

A: In competition, it is strongly recommended to change the discs before pair (left and right simultaneously). This ensures a perfect balance of braking during deceleration phases. If one side brakes stronger than the other because of an asymmetric wear of the disks, the kart will tend to pull on one side braking, which hurts the stability of the front train.
