Porsche 911 Turbo

Longer-lasting and better-performing, a new ceramic composite brake provides more “stop” to a car that is all about “go.”

Porsche AG claims it is the first carmaker in the world to introduce a ceramic composite brake with involute (spiral-shaped) cooling ducts. The Porsche Ceramic Composite Brake (PCCB) is offered as an option on the new Porsche 911 Turbo and can be retrofitted to 911 models ordered without the option.

PCCB offers advantages in performance, weight, and maintenance, according to the company. The disc is based on a three-phase system with specially treated carbon fibers silicated in a high-vacuum process at a temperature of 1700°C (3100 °F). Like Porsche's conventional metal brake disc, the ceramic type is cross-drilled and vented from inside.
