If the electric parking brake could not be applied fully when the vehicle is stopped, the brake warning light on the instrument panel starts to flash.

For information on warning messages on the multi-function display:

  • Please see the chapter "OVERVIEW OF WARNING AND INFORMATION MESSAGES" on page 126.


  • 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 (100 km/h), for example, it is not twice but four times longer than 30 mph (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 disks consist of alloyed gray 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 road salt or grit was spread and whether grease-dissolving agents were used in car washes.

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 disk brakes at the front and rear.

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

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.

Brake Hydraulic Failure Recovery

Your vehicle is equipped with an emergency function in the extreme event of a complete hydraulic failure of the brake system. If your brake pedal goes all the way to the floor, do not pump the brakes.

  • 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.

Brake system warning light
You can check the functionality of the brake system warning light by switching the ignition to the "On" position (position 1) and verifying that the warning light illuminates.

The warning light in the instrument panel lights up. A message will be displayed on the multi-purpose display of the instrument panel if the brake fluid level is too low, or (if the brake pedal travel has increased) one of the two brake circuits has failed.

A greater braking pressure will be required, stopping distances will be longer and the braking behavior will change, particularly in curves.
