SCROLL TO DISCOVER THE FEATURES OF CARBON CERAMIC DISC
Carbon ceramic braking band, guaranteeing approximately 50% less weight than cast iron discs
Aluminum hat that reduces the overall weight of the disc and enhances heat dissipation, while preventing deformation at high temperatures
The carbon ceramic braking band guarantees high temperatures and corrosion resistance
Key benefits
Carbon ceramic discs weigh approximately 50% less than cast iron discs.
This helps reduce the overall weight of the car, improving control, acceleration and reactions while driving.
Performance data indicates that carbon ceramic discs have a coefficient of friction 25% higher than traditional discs and more stable at high temperatures.
Therefore, they offer more effective braking on dry and wet roads.
Thanks to their composition, carbon ceramic discs are highly resistant to corrosion and high temperatures.
This feature makes them suitable for long-lasting and reliable use.

Carbon ceramic discs give the best when combined with Brembo Carbon ceramic brake pads. Together, they guarantee uncompromising excellence in performance and driving comfort.
A special feature of the carbon ceramic brake discs is represented by the ceramic composite material. This material is obtained through a particular process, which gives the possibility to add or deposit a layer of material to improve the friction coefficient on both the braking surfaces.
The core and the additional friction layer are made by a composite material, which is composed by carbon fibers (reinforcement), silicon carbide and metallic silicon (matrix).
Silicon carbide, the main matrix component, assures great hardness for the composite material while carbon fibers guarantee high mechanical strength resistence, providing the fracture toughness required in this kind of applications.
The production of a carbon ceramic brake disc spans approximately 20 days. The process begins with carbon fibers, which are given a special protective coating and cut into short fiber sections of defined thickness and length. These fibers can be used directly or treated to create a complex raw material called "carbochip."
The production process starts with mixing the components and culminates in assembling the rotor and bell. The ceramic brake body is formed by pressing a preform with binding resin into a "green body," which is then converted into the ceramic component through a two-step process: carbonization at 900°C, followed by liquid silicon infiltration (siliconization) at 1700°C in a vacuum atmosphere.
One of the intricate aspects of the manufacturing process is the "lost core" technology, where a plastic matrix defines the cooling channel geometry and burns out without residue during carbonization. Another complexity is the use of different fiber components for the brake disc body, the friction layers on the ring exterior, and the point-shaped abrasion indicators integrated into the friction layer. The final machining requires advanced technology, as the material's hardness necessitates the use of diamond tools.
