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 peddle goes all the way to the floor, do not pump the brakes.
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.
Brake warning light USA
Brake warning light Canada
The warning light in the instrument panel lights up. A message will be displayed on the multi-function 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.
With correctly adjusted brakes and a correctly working brake system, the pedal travel to the point of brake application should be 1-3/16 in. to 1-9/16 in. (30 to 40 mm). Whenever the brake pedal travel exceeds this value, have the brake system checked.
Obstruction of Brake Pedal
Unsuitable or incorrectly fixed floor mats or objects can reduce the travel of the brake pedal or prevent you applying the brake pedal.
In case one of the two brake circuits fails, increased pedal travel is required to bring your vehicle to a full stop.
