Brake booster 

the engine is running. 
When the car is moving while the engine is not run-

ning, or if the brake booster is defective, more 

pressure on the brake pedal is required to bring 

the car to a stop. 

Moisture or road salt

Moisture or road salt on brakes affects braking.

When the vehicle is driven on salted roads for ex-

tended periods, the brakes should be washed 

down thoroughly about every 2 weeks. 

Brakes will dry after a few cautious brake applica-

tions. 

braking efficiency. 
f Cautiously apply brakes to test brakes after 

such exposures. 

Brake wear 

Your car has excellent brakes, but they are still 

subject to wear. The rate at which they wear de-

pends on how the brakes are used. 
f Have the brake system inspected at the 

intervals recommended in your Maintenance 

Booklet. 

If the warning lights in the instrument panel and on-

board computer stay on when the engine is run-

ning or come on while driving, the brake pads are 

worn, excessively. 
f Do not continue to operate the vehicle.

Have your authorized Porsche dealer inspect 

or replace the brake pads. 

Brake pads 

Wear on the brake pads and brake discs depends 

to a great extent on the driving style and the con-

ditions of use and therefore cannot be expressed 

in actual miles on the road. 
The high-performance brake system is designed 

for optimal braking effect at all speeds and tem-

peratures.

Certain speeds, braking forces and ambient 

conditions (such as temperature and humidity) 

may cause “brake noises”.

New brake pads or linings 
New brake pads and brake discs have to be “bro-

ken in”, and therefore only attain optimal friction 

when the car has covered several hundred miles 

or km.

The slightly reduced braking ability must be com-

pensated for by pressing the brake pedal harder. 

This also applies whenever the brake pads and/or 

brake discs are replaced.
