We would like to speed up everything. Even development. This applies also to negative acceleration. As even in a topic like braking, there is potential.
This is why we adjusted in the 911 the dimensioning of the brake system to the engine performance. The basic 911 models are installed with four-piston monobloc aluminium fixed calipers with black anodised finished. The disc brake diameter front and back is 330 mm.
The S-models are supplied with red six-piston monobloc aluminium fixed calipers at the front and four-piston monobloc aluminium fixed calipers at the rear. The brake covers at the front axle are manufactured in aluminium. The brake disc diameter is 350 mm at the front and 330 mm at the back. For improved brake performance and stability.
The calipers are locked in all models. The advantages:
higher inherent stability, better pressure point behaviour even with extreme loads, and low weight. The pedal travel is short, the pressure points accurate. The brake discs are cross-drilled to provide better brake reaction even in wet conditions, as well as optimal cooling.
