Audi ceramic brakes offer outstanding deceleration rates, long service life, light weight and sporty looks.
Audi ceramic brake discs are made from carbon-fibre-reinforced ceramics. This type of material composition is a so-called composite ceramic material. Its base material is silicon carbide, which is extremely hard and highly resistant to wear and has a crystalline structure similar to a diamond. High-strength carbon fibres are embedded in the structure, and these prove an effective means of absorbing the stresses which occur in the material.
The sophisticated geometry of the cooling channels in the ventilated brake discs provide for outstanding brake disc cooling. Compared to steel brake discs of an identical design, the service life is much longer (under the same operating conditions) due to the high resistance to wear. The result is a high-performance brake system made of carbon-fibre-reinforced ceramic material which is especially well suited for high loads.
The special material characteristics of the composite ceramics and the high-performance configuration mean certain brake noises specific to ceramic brakes could occur at walking pace. When wet or exposed to road salts (e.g. after going through a car wash, overnight dew, etc.) the braking effect may correspond to that of a conventional brake system. This reduced braking effect will be noticeable to the driver as they will already have become accustomed to the high braking standards of the ceramic brake system – greater pedal pressure can compensate for this.
