e Whenever the brake pedal travel exceeds this
value, have the brake system checked. Visit an
authorized Porsche dealer. Porsche recommends
an authorized Porsche dealer, as they have
trained technicians and the necessary parts and
tools.
Brake pads and brake disks
The wear on the brake pads and brake disks largely
depends on the driving style and the conditions of
use and cannot therefore be expressed in terms of
mileage covered.
The high performance brake system is designed to
ensure the best possible braking effect at all speeds
and temperatures.
Braking noise may occur, depending on the speed,
braking force and ambient conditions (e.g., temper-
ature, humidity).
e
Have the brake system inspected at the intervals
recommended in your Maintenance Booklet.
Responding to warning symbols
The functionality of the brake system warning light
can be checked by switching the ignition to the “On”
position (position 1 ) and verifying that the warning
light illuminates.
Brake wear warning light USA
Brake wear warning light Canada
A warning message is displayed to indicate that the
brake pads are reaching their wear limit.
> Please see chapter "Warning and Information
Messages" on page 280.
e Have the brake pads replaced immediately. Visit
an authorized Porsche dealer. Porsche recom-
mends an authorized Porsche dealer, as they
have trained technicians and the necessary parts
and tools.
Porsche Ceramic Composite Brake (PCCB)
The high performance brake system is designed to
ensure the best possible braking effect at all speeds
and temperatures.
The wear of various components of the braking sys-
tem, such as brake pads and brake disks, largely de-
pends on the individual driving style and the
conditions of use and thus cannot be expressed in
terms of mileage covered.
The values quoted by Porsche are based on normal
use in line with general traffic conditions. Wear in-
creases significantly if the vehicle is used on race-
tracks or if a forceful driving style is adopted.
e Before driving your vehicle in this way (e.g. on
race tracks), ask an authorized Porsche dealer
about currently applicable guidelines.
Porsche Surface Coated Brakedisc (PSCB)
The high-performance brake system is designed for
optimal protection against wear and corrosion on
friction surfaces. Wear on different components of
the brake system, e.g. brake disks or brake pads,
depends to a great extent on the individual driving
style and therefore cannot be expressed in actual
miles on the road. In addition to the advantages
listed here, the innovative hard coating of the brake
disk friction surfaces gives the disks a very specific
look and cannot be compared with a standard brake
disk. Owing to the hard-coated brake disk, a longer
bedding-in period of the PSCB must be taken into
account, during which a technically insignificant
friction noise may occur. When a vehicle is driven
normally in line with traffic conditions, a shiny
chrome-like friction surface covered with fine cracks
appears after several thousand kilometers. Wear,
cracks and darkening of the shiny silver friction sur-
face increase when the vehicle is driven on race
tracks or if a forceful driving style is adopted. These
visual changes have no relevant effect on braking
and often only partially disappear after driving sev-
eral thousand kilometers.
e Before driving your vehicle in this way, ask your
Porsche partner about currently applicable
guidelines.
