WARNING: This page is about a different car, the 2010 Porsche Cayenne, 2009 Porsche Cayenne, and 2008 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.

A foot-operated parking brake is used in the Porsche Cayenne.

Special demands for a sporty, multi-purpose vehicle have been taken into account when designing the foot-operated parking brake. To achieve the required capabilities, it was designed as a foot-activated parking brake with an intermediate transmission ratio. The Cayenne can be parked reliably with a full load on gradients of 55 %.

A cable is routed from the foot-operated lever to a deflection lever under the centre console which transmits traction to a turnbuckle with a transmission ration of 3.1. Two cables are routed from the turnbuckle to the parking brakes on the rear axle.

The foot-operated parking brake is designed as a duo-servo drum brake and is integrated into the rear brake discs.
