2012 All-New Porsche Carrera: Porsche Ceramic Composite Brake (Part 9/12)

PORSCHE Euorpe: Official Press Release

The new Porsche 911 Carrera

Higher Braking Force and Parking Brake

To align braking performance with the enhanced driving performance, the new 911 Carrera models come with a newly developed and more efficient eight-/nine-inch, lightweight-aluminium construction, tandem brake booster, which is 800 grams lighter than the previous component into the bargain.

The Carrera features an optimised braking system with weight-reduced brake discs. Front-mounted, six-piston aluminium monobloc fixed calliper brakes and integral 340 millimetre (13.4 inch) diameter disc brakes (ten millimetres more compared with the predecessor model) are making their debut appearance on the 400 hp 911 Carrera S. Rear axle braking power in all models is provided by four-piston aluminium monobloc fixed-calliper brakes and 330 millimetre (13.0 inch) diameter brake discs. Brake cooling has been further optimised. Cooling air from the underbody air flow is directed onto the front and rear brakes.

The 911 Carrera's modernised braking concept relieves the driver of a further task: there is no longer a handbrake lever. Porsche is fitting an electrically activated parking brake in the Carrera for the first time. It is operated by means of a button conveniently located to the left of the steering wheel.

The new 911 Carrera models also are available with the tried and tested Porsche Ceramic Composite Brake (PCCB) with ceramic disc brakes and new six-piston monobloc fixed callipers on the front axle as an option.

Larger wheels and tyres: Lightweight construction and smooth running for greater efficiency

Lightweight construction considerations also played a decisive role in developing the new family of wheels. This is why it is manufactured using the weight-saving flow-forming process. In addition to lower fuel consumption, lighter wheels also mean a reduction of unsprung masses and thus a more comfortable ride. The 911 Carrera now runs as standard on 19-inch Carrera wheels in a five double-spoke design and new high-gloss silver with 20 millimetre wider rear tyres. The 911 Carrera S features the new Carrera S 20-inch wheel. All 20-inch wheels are finished in a new premium high-gloss silver. A visual highlight in the wheel range is the new 20-inch Carrera Classic wheel in a bi-colour design. Optional wheel hub covers with coloured Porsche crest are available for all wheels.

The tyre manufacturers collaborated with Porsche on a new product generation, yielding further improvements in performance, comfort, rolling resistance, handling and braking distance as well as weight. The seven per cent reduction in rolling resistance compared with earlier tyres makes a major contribution to reducing fuel consumption.
