Porsche Ceramic Composite Brake (PCCB)

Cayenne S Hybrid

Porsche Ceramic Composite Brake (PCCB)

Available as an option on all Cayenne models, the Porsche Ceramic Composite Brake (PCCB) has already proven its ability to cope with the harshest requirements of the racetrack. It is available in conjunction with 20-inch wheels or larger for the Cayenne Turbo and with 19-inch wheels or larger for all other Cayenne models.

The discs are made from a specially treated carbon-fibre compound that is silicated in a high-vacuum process at approximately 1,700 °C. The resulting material is not only much harder than cast iron, it is also more resistant to heat.

Even at high temperatures, the thermal resistance of the PCCB disc ensures outstanding dimensional stability. The ceramic material is totally resistant to corrosion and offers excellent acoustic damping properties.

PCCB enables shorter braking distances – no matter how tough the driving conditions. The pedal response is fast and precise with only moderate input required. Excellent fade resistance ensures greater balance when slowing from high speed.

The key advantage of PCCB is a total weight saving of approximately 50% compared with equivalent cast-iron discs. As well as enhancing performance and fuel economy, the unsprung and rotating masses are lightened. The results: greater comfort and road-holding on uneven road surfaces plus better handling and agility.

Optional for all Cayenne models.
