Brake Caliper: Description and Operation

Brakes

To ensure that the high requirements with regard to the braking performance of a Porsche are met even better than before, all new Cayenne models are equipped with an even larger and optimized brake system. The brake systems can be identified visually according to the familiar logic: black brake calipers identify the Cayenne, silver brake calipers the Cayenne S and red brake calipers the Cayenne Turbo. The racing-proven Porsche Ceramic Composite Brake (PCCB) is optionally available for all Cayenne models.
