The warning lights in the instrument panel and onboard computer will go out after the parking brake is fully released.

The warning lights are not an indicator that the parking brake is fully set; it is only intended to be a warning to release the parking brake before driving the car.



A partially engaged brake will overheat the rear brakes, reduce their effectiveness and cause excessive wear.

  • Release the parking brake fully.


  • When parking your car, always set the parking brake by pulling all the way up on the lever.
  • Move the selector lever to "P" (PDK) or move the gearshift lever to reverse or first gear (Manual transmission).
  • On hills also turn the front wheels towards the curb.

Brakes

  • Make it a habit to check the operation of your brakes before driving.

Keep in mind that the braking distance increases very rapidly as the speed increases. At 60 mph or 100 km/h, for example, it is not twice but four times longer than 30 mph or 50 km/h. Tire traction is also less effective when the roads are wet or slippery.

  • Therefore, always maintain a safe distance from the car in front of you.

Vehicles without Porsche Ceramic Composite Brake (PCCB)
Even though the brake discs consist of alloyed grey cast iron, they will unavoidably start to corrode if your car is parked for an extended period. The brakes will tend to "rub" as a result.

The nature, extent and effects of corrosion depend on the amount of time the vehicle was parked, whether granular or liquid road salt was spread and whether grease-dissolving agents were used in car washes.

To prevent corrosion of the brake discs, "brake them dry" before parking the car.

If the braking comfort is noticeably impaired, we recommend having the brake system checked by experts at an authorized Porsche dealer.

Brake system function
Your Porsche is equipped with a power assisted hydraulic dual circuit brake system with disc brakes at the front and rear.

Both circuits function independently. One brake circuit operates the front and the other operates the rear.

If one brake circuit has failed, the other will still operate. However, you will notice an increased pedal travel when you apply the brakes.

Failure of one brake circuit will cause the stopping distance to increase.



Risk of an accident, resulting in serious personal injury or death.

In the unlikely event of hydraulic failure of one brake circuit:

  • Push the brake pedal down firmly and hold it in that position.
    A mechanical linkage activates the second circuit, and you will be able to bring the vehicle to a stop.
  • After bringing your vehicle to a complete stop, avoid driving the vehicle and instead have it towed to the nearest authorized Porsche dealer for repair.
