Brakes

Another crucial piece of the Porsche identity is the brakes. We value them as highly as we do our engines and chassis. They set standards for deceleration and stability, and give the driver the reassurance needed to push the car to the limits of its performance.

The 911 Carrera base models are fitted front and rear with anodized black four-piston aluminum monobloc fixed calipers. All brake discs have a diameter of 13 inches (330 mm).

On the S models, we have fitted larger brakes and more brake pistons to cope with the higher engine power of these models. Consequently, they feature red six-piston monobloc aluminum fixed brake calipers at the front and four-piston aluminum monobloc fixed calipers at the rear. The brake disc diameter is 13.4 inches (340 mm) at the front and 13 inches (330 mm) at the rear. The results are enhanced braking performance and stability.

On all models, the brake calipers have an enclosed monobloc construction. This makes them tougher but lighter and enables a more rapid response and release of the brake even under extreme loads. The pedal travel is short and the biting point precise. The brake discs are cross-drilled for better performance in the wet.

Other benefits of the standard braking system include the anti-lock braking system (ABS), designed to keep deceleration constant. Pedal effort is reduced and braking response improved by an 8-/9-inch tandem vacuum brake booster. In the S models, brake disc cooling is further enhanced by modified air spoilers.
