Brakes 911 Turbo S Cabriolet

Porsche 911 Turbo S Cabriolet - Brakes

Brakes

Positive: negative acceleration. For us, it goes without saying that the 911 Turbo models should also be setting standards with their brakes. We value them as highly as we do our engines and chassis. With reference values for deceleration and stability. Giving the driver the reassurance needed to push the car to the limits of its performance.

So, in the 911 Turbo and the 911 Turbo Cabriolet the brakes have been adapted to meet the demands of higher performance. They feature red six-piston monobloc aluminium fixed brake calipers at the front and four-piston aluminium monobloc fixed calipers at the rear. The brake disc diameter is 380 mm front and rear.

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 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. Brake disc cooling is optimised by air spoilers.

Electric parking brake

The electric parking brake, which you can activate and deactivate manually, releases automatically as you pull away.

With the hill-hold function, you can pull away without ever rolling back. The system automatically detects when the vehicle has come to a halt on an uphill gradient requiring intervention. PSM then maintains the brake pressure at all four wheels to prevent the vehicle from moving in the opposite direction.

Porsche Ceramic Composite Brake (PCCB)

Porsche has been synonymous with motorsport right from the start. And we have taken the experience we have gained on the racetrack and applied it to the road. The Porsche Ceramic Composite Brake (PCCB), which is standard equipment in the 911 Turbo S models and available as an option for the 911 Turbo models, is a fine example. This brake system has already had to cope with the harshest requirements of motor racing and is fitted in cars that compete in demanding events such as the Porsche Mobil 1 Supercup.

The cross-drilled PCCB ceramic brake discs have a diameter of 410 mm at the front and 390 mm at the back – for even more formidable braking performance.

The use of six-piston aluminium monobloc brake calipers on the front axle and four-piston aluminium monobloc units at the rear – all finished in yellow – ensures extremely high brake forces which, crucially, are exceptionally consistent.

PCCB enables shorter braking distances in even the toughest road and race conditions. Excellent fade resistance guarantees greater balance when slowing from racetrack speeds.

The key advantage of PCCB is the extremely low weight of the ceramic brake discs, which are approximately 50 % lighter than standard discs of similar design and size. As well as enhancing performance and fuel economy, this represents a major reduction in unsprung and rotating masses, resulting in better roadholding and increased comfort, particularly on uneven roads, as well as greater agility and improved handling.

The demands of racetrack use mean that additional maintenance tasks will be required alongside the routine maintenance work scheduled as part of standard maintenance intervals.
