Positive: negative acceleration. For us, it goes without saying that the new 911 Turbo models should also be setting new 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 new 911 Turbo we have adapted the brakes to suit the higher performance. It features 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 optimized by air spoilers.
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.
