2010 PORSCHE 911 CARRERA brakes

4Sport tiresSport tires (ultra high performance tires) are ap-
proved for use on public highways and comply
with all statutory requirements and safety criteria.
The design of the tire is also geared towards use
on racing circuits (driver safety training courses,
sports driving schools, Club Sport events) and
provides distinct advantages here in terms of dry
grip and wear compared to conventional road
tires.
The major features are a reduced tread depth and
a special tread pattern and carcass.
The design features of this sports tire result
in the following effects compared with other
summer tires when used under normal
driving conditions:
– Sport tires have a smaller tread depth, and
thus can reach their wear limit sooner.
As with all tires, the attainable mileage de-
pends on the individual driving style and the
conditions of use.
– Exercise caution when driving on wet roads,
paying special attention to hydroplaning situa-
tions (stagnant water, puddles, lane grooves).
Sport tires have a lower tread depth than nor-
mal tires and you must therefore adapt speed
accordingly when driving on wet surfaces.– The driver’s skill level must be commensurate
with the vehicle performance levels in the up-
per range limits, due to increased safety risks
in the upper range limits.
fAt oudside temperatures below 45 °F (7 °C)
change to snow tires.
fNotify anyone using your car of these charac-
teristics and possible effects.
Danger!
Risk of accident through loss of road surface
contact, control over the vehicle and braking
ability, leading to serious personal injury or
death.
The reduced tire tread depth means that
there is an increased risk of aquaplaning on
wet roads.
fWhen driving on wet or mud-covered roads re-duce speed significantly. Danger!
Risk of accident from worn tires.
Sport tires have a smaller tread depth, and
thus can reach their wear limit sooner.
It is important to check tire wear frequently
to avoid risk of serious personal injury or
death from worn tires.
fCheck tire wear frequently.
Porsche Ceramic Composite Brake
(PCCB)fPlease see the chapter “BRAKES” on Page 58.
The high-performance brake system is designed
for optimal braking effect at all speeds and
temperatures.
Certain speeds, braking forces and ambient
conditions (such as temperature and humidity)
therefore might cause brake noises.
Wear on the different components and braking
system, such as brake pads and brake discs,
depends to a great extent on the individual driving
style and the conditions of use and therefore
cannot be expressed in actual miles on the road.
The values communicated by Porsche are based
on normal operation adapted to traffic. Wear
increases considerably when the vehicle is driven
on race tracks or through an aggressive driving
style.
fPlease consult an authorized Porsche dealer
about the current guidelines in effect before
such use of your vehicle.

Operation, Safety The warning lights in the instrument panel and on-
board 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. Caution!
A partially engaged brake will overheat the
rear brakes, reduce their effectiveness and
cause excessive wear.
fRelease the parking brake fully.
fWhen parking your car, always set the parking
brake by pulling all the way up on the lever.
fMove the selector lever to “P” (PDK) or move
the gearshift lever to reverse or first gear
(Manual transmission).
fOn hills also turn the front wheels towards the
curb.
Brakes fMake 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 trac-
tion is also less effective when the roads are wet
or slippery.
fTherefore, always maintain a safe distance
from the car in front of you.
Vehicles without Porsche Ceramic Compos-
ite Brake (PCCB)
Even though the brake discs consist of alloyed
grey cast iron, they will unavoidably start to cor-
rode 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 de-
pend 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 op-
erate. 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.
Warning!
Risk of an accident, resulting in serious per-
sonal injury or death.
In the unlikely event of hydraulic failure of
one brake circuit:
fPush the brake pedal down firmly and hold it in
that position.
A mechanical linkage activates the second cir-
cuit, and you will be able to bring the vehicle to
a stop.
fAfter bringing your vehicle to a complete stop,
avoid driving the vehicle and instead have it
towed to the nearest authorized Porsche deal-er 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 and verifying that the warning
light illuminates.
If the warning lights in the instrument panel and on-
board computer go on while driving, the brake flu-
id level may be too low, or (if the brake pedal travel
has increased) one of the two brake circuits may
have failed.
A greater braking pressure will be required, stop-
ping distances will be longer and the braking be-
havior will change, particularly in curves.
With correctly adjusted brakes, and a correctly
working brake system, the pedal travel to the
point of brake actuation should be 1-3/16 in. to
1-9/16 in. or 30 to 40 mm.
Whenever the brake pedal travel exceeds this dis-
tance, have the brake system checked.
Brake pedal
Warning!
Risk of an accident, resulting in serious per-
sonal injury or death.
Any obstruction of the brake pedal could
increase the stopping distance.
fAlways check the movement of the brake pedal
before driving and make sure that it is not ob-
structed by a floor mat or any other object.
fSecure the floor mat to prevent it from sliding
into positions that could interfere with the safe
operation of your vehicle.
Your Porsche dealer will be glad to offer you nonskid floor mats of the correct size.
Note
In case one of the two brake circuits fails, in-
creased pedal travel is required to bring your
vehicle to a full stop.
Warning!
To avoid overheating and premature wear of
the brakes:
fBefore descending a steep grade, reduce
speed and shift the transmission into a lower
gear or driving position to control speed.
fDo not “ride the brakes” by resting your foot on
the pedal when not intending to apply brake
pressure.
fDo not hold the pedal down too long or too
often.
This could cause the brakes to get hot and not function properly.

Operation, Safety
Brake booster The brake booster assists braking only when
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.
If this happens, ABS and PSM will also not oper-
ate.
Moisture or road salt on brakes affects braking.
When the vehicle is driven on salted or sanded
roads for extended periods, the brakes should be
washed down thoroughly about every 2 weeks. An
automatic carwash facility cannot do this job prop-
erly.
Brakes will dry after a few cautious brake applica-
tions.
Warning!
Risk of an accident, resulting in serious per-
sonal injury or death.
Driving through water may reduce the trac-
tion.
Moisture on brakes from road water, car
wash, or coating of road salt may affect
braking efficiency.
fCautiously apply brakes to test brakes after ex-posure to road water, etc.
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.
fHave the brake system inspected at the
intervals recommended in your Maintenance
Booklet.
Brake system warning light
You can check the functionality of the brake
system warning light by switching the ignition to
the "On" position and verifying that the warning
light illuminates.
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.
fDo 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)
therefore might 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
brake discs are replaced.

Operation, Safety
Porsche Stability Management
(PSM)PSM is an active control system for stabilization of
the vehicle approaching the performance limits of
driving maneuvers.
Warning!
Risk of an accident, resulting in serious per-
sonal injury or death.
The increased control that is provided should
not induce you to take greater risks with your
safety. The limits dictated by the laws of
physics cannot be overcome, even with PSM.
The risk of accidents due to inappropriate
speed cannot be reduced, even by PSM.
The driver bears the responsibility for all
driving maneuvers.
fAdapt your driving style to the prevailing road
and weather conditions.
fObey all traffic laws.
Sensors at the wheels, brakes, steering system
and engine continuously measure:
–Speed
– Direction of travel (steering angle)
– Lateral acceleration
– Rate of turn about the vertical axis
– Longitudinal accelerationPSM uses these values to determine the direction
of travel indicated by the driver.
PSM intervenes and helps to correct the course if
the actual direction of motion deviates from the
chosen course (steering-wheel position):
It brakes individual wheels as needed. In addition,
the engine power may be manipulated in order to
stabilize the vehicle.
The events below inform the driver of PSM control
operations and warn him/her to adapt his/her
driving style to the road conditions:
– The multifunctional information light on the
instrument panel flashes.
– Hydraulic noises can be heard.
– The vehicle decelerates and steering-wheel
forces are altered as the PSM controls the
brakes.
– Reduced engine power.
– The brake pedal pulsates and its position is
changed during braking.
In order to achieve full vehicle deceleration,
foot pressure must be increased after the
brake pedal has begun vibrating.
Examples of PSM control operations– If the front wheels of the vehicle drift on a
bend, the rear wheel on the inside of the bend
is braked and the engine power is reduced if
necessary.
– If the rear of the vehicle swings out on a bend,
the front wheel on the outside of the bend is
braked.Additional braking functions– Pre-filling the brake system:
The brake system is prepared for possible
subsequent emergency braking if the acceler-
ator pedal is released suddenly and quickly.
The brake system is prefilled and the brake
pads are already applied gently to the brake
discs.
– Brake booster:
In the event of an emergency braking operation
where the pedal force is insufficient, a brake
booster provides the braking pressure neces-
sary for maximum deceleration at all 4 wheels.Advantages of PSM– Best possible traction and lane-holding ability
in all driving situations – even on road surfaces
with varying friction.

Operation, Safety
67
– The system compensates for undesired lateral
vehicle reactions when the driver releases the
accelerator pedal or brakes when cornering.
This compensation functions up to the
maximum lateral acceleration.
– PSM actively stabilizes the vehicle as required
during dynamic driving maneuvers (e.g. rapid
steering movements, during lane changes or
on alternating bends).
– Improved braking stability on bends and on
different or varying road surfaces.
– It improves braking function and shortens
stopping distance in the event of emergency
braking.Readiness for operationPSM is switched on automatically every time you
start the engine.
PSM should always be switched on during
“normal” driving.
However, it may be advantageous to switch off
PSM temporarily in exceptional situations, for
example:
– On a loose surface or in deep snow,
– When “rocking” the vehicle free and
– When using snow chains.
Switching off PSMfPress PSM OFF button.
PSM is switched off after a short delay.
The light-emitting diode in the button is lit up.
When the PSM is switched off, the PSM multi-
functional light on the instrument panel is lit
and a message is shown on the on-board
computer.
An acoustic signal also sounds.
Note
When PSM is switched off, the additional braking
functions are deactivated. Automatic reactivation
in emergency situations is linked to the PSM
control.The following functions stabilize the vehicle in
emergency situations, even with PSM switched
off:
– When PSM is off, the vehicle is stabilized as
soon as one of the two front wheels enters the
ABS control range.
– When PSM is off and Sport mode is on, the
vehicle is stabilized as soon as both front
wheels enter the ABS control range.
One-sided spinning of the wheels is prevented,
even with PSM switched off.
Switching PSM back onfPress PSM OFF button.
PSM is switched on after a short delay.
The light-emitting diode in the button and the
PSM multifunctional light on the instrument
panel go out.
The on-board computer shows a message.
