Braking system


Performance is reflected in excellent acceleration values. And we take account of both positive and negative acceleration. Which is why Porsche also traditionally sets standards for stopping power and stability. Braking power is a multiple of engine power.

The Boxster models are equipped with four-piston aluminium monobloc fixedcaliper brakes. This design means that, not only are the brakes extremely resistant to deformation, they are lightweight for a particularly fast and sensitive braking response. Even during continuous use. Brake cooling has also been optimised by the brake ventilation system with air spoilers at the front and rear axles.

The dynamics of the Boxster models also demand appropriate brake discs. These are internally vented and cross-drilled for improved braking in wet conditions. With a diameter of 330 mm, the front brake discs of the Boxster S and Boxster GTS are 15 mm larger than those of the Boxster. The diameter of the rear brake discs is 299 mm on all models.

Porsche Ceramic Composite Brake (PCCB)

The optional Porsche Ceramic Composite Brake (PCCB) has proven itself in motorsport. The cross-drilled brake discs have a diameter of 350 mm front and rear for even more formidable braking performance.

The use of six-piston aluminium monobloc fixed brake calipers on the front axle and four-piston units at the rear – all painted yellow – ensures extremely high brake forces which, crucially, are exceptionally consistent. PCCB enables shorter braking distances in even the toughest road and race conditions.

Another 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 also represents a major reduction in unsprung and rotating masses. The consequence of this is better roadholding and increased comfort, particularly on uneven roads.

In addition to the regular servicing work performed within the standard service intervals, additional servicing should be performed if used on the race track.

Electric parking brake

The electric parking brake, which can be activated and deactivated manually, is released automatically as you pull away with your seat belt fastened. A hold function is integrated as standard. It assists you in making a comfortable, smooth and roll-free start on an incline.
