2021 NISSAN GT-R brakes

For models without NCCB (NISSAN Car-
bon Ceramic Brake) package:
NISSAN generally recommends to replace
all four sets of brake pads and disc rotors
at the same time to maintain maximum
brake performance.However, replacing only the brake pads
may be allowed in some cases (four
wheels or only front wheels depending
on the conditions). A GT-R certified tech-
nician must inspect the vehicle and
determine that only the brake pads need
to be replaced. In this case, replacing all
brake pads and disc rotors as a set is not
necessary.
Note that the replacement of brake pads
and the disc rotors as a set on all four
wheels should be performed when a GT-R
certified technician determines that this
is the correct repair.
If the inside of the disc rotors are cold
during the winter and the surface be-
comes hot due to a heavy force being
applied repeatedly to the brakes, cracks
may occur near the coolant hole on the
surface of the disc rotor. Cracks may also
occur due to a heavy force being repeat-
edly applied to the brakes during high
performance driving. In these cases it
may be necessary to replace the disc
rotors or brake pads depending on the
condition of the crack. We recommend
contacting a GT-R certified NISSAN dealer
for replacement.

in this section for 48 hours after tires
are installed on the wheels. The tire
may slip on the wheel if the vehicle is
driven in these conditions before 48
hours have passed. If the tire slips on
the wheel, the wheel/tire assembly
will be out of balance and will require
rebalancing.
BrakesThe information and specifications in
this section apply only when engaging
in performance driving.
.Check for the heat deterioration of the
brakes and parts around the brakes.
. It is recommended that you remove
air from the brake system after any of
the following:
— When engaging in high perfor-
mance driving for the first time
after purchasing a new vehicle.
— After replacing the brake fluid.
— When engaging in high perfor- mance driving for a sustained per-
iod of time. It is recommended that
bleeding the brake be performed
when the brake calipers are hot
(about 212°F (100°C)). Brake pad break-in procedure:
NISSAN recommends that a special brake
pad break-in procedure be performed
before engaging in performance driving.
It is recommended you contact a GT-R
certified NISSAN dealer for details.
INSPECTION AND ADJUSTMENTS
AFTER DRIVINGThe information and specifications in
this section apply only when engaging

BRAKE SYSTEM INFORMATION
Cracks on brake padThe friction material of the GT-R disc
brake pad is bonded to the pad backing
plate more strongly than conventional
brake pads to withstand the high brake
temperatures. The friction material and
backing plate expand due to heat at
different rates. Some cracks may be on
the surface of the friction material due to
the differences in expansion rates and the
strong bond between the friction material
and backing plate. The cracks do not
indicate the brake pads need to be
replaced. However, depending on the
condition of the cracks, the pads may
need to be replaced. It is recommended
you contact a GT-R certified NISSAN deal-
er.
. This is due to the temperature
differential that occurs because the sur-
faces of the disc rotors become hot while
the inside of the rotor is still cold. How-
ever, this poses no problem in terms of
brake performance, and does not indicate
a malfunction. The brakes do not need to

NOTICE
.When the temperature of the
engine coolant and transmission
oil is high or low, the function
cannot be used. The temperature
range in which the R mode start
function can be used:
— Engine coolant: 140°F - 212°F
(60°C - 100°C)
— Transmission oil: 140°F - 266°F (60°C - 130°C)
. If the R mode start function is
used 4 times consecutively, the
function may be disabled and
cannot be turned on to protect
the vehicle system. While the function is disabled, the warning
light illuminates. When the warn-
ing light illuminates, perform cool
down driving. (
“Cool down”
page GTR-14) When the warning
light turns off, the function can be
used again.
. The performance of start may
vary depending on the amount
of wheel spin ,or increase and
decrease of the engine output in
response to the outside tempera-
ture. (This vehicle was set up
according to the road surface
conditions of the straight sec-
tions of the Sendai Highland Ra-
ceway course in Japan at 59°F
(15°C).)
. For safety reasons, VDC control
may activate automatically when
driving on a slippery road surface,
such as a wet road, in order to
apply the brakes or limit the
engine output.
. Frequent use of the R mode start
function increases the load on
the powertrain related parts such
as the clutch and transmission
compared to normal driving. In
particular, the clutch will wear out

NOTICE
When the vehicle is stopped on a hill,
do not hold the vehicle in place by
depressing the accelerator pedal.
Doing so may cause the clutch to
overheat and result in transmission
damage. Use the brakes to prevent
the vehicle from moving.
The hill start assist system automatically
keeps the brakes applied to help prevent
the vehicle from rolling backwards in the
time it takes the driver to release the
brake pedal and apply the accelerator
when the vehicle is stopped on a hill.
Hill start assist will operate automatically
under the following conditions:
. The shift lever is moved to a forward
or reverse position.
. The vehicle is stopped completely on a
hill by applying the brake.
The maximum holding time is 2 seconds.
After 2 seconds the vehicle will begin to
roll back and hill start assist will stop operating completely.
Hill start assist will not operate when the
shift lever is moved to the
or
position
or on a flat and level road.

3. To help prevent the vehicle from roll- ing into the street when parked on a
sloping drive way, it is a good practice
to turn the wheels as illustrated.
.
HEADED DOWNHILL WITH CURB:Turn the wheels into the curb and
move the vehicle forward until the
curb side wheel gently touches the
curb.
.
HEADED UPHILL WITH CURB:Turn the wheels away from the
curb and move the vehicle back
until the curb side wheel gently
touches the curb.
.
HEADED UPHILL OR DOWNHILL, NO
CURB:Turn the wheels toward the side of
the road so the vehicle will move
away from the center of the road if
it moves.

For models without NCCB (NISSAN Car-
bon Ceramic Brake) package:
The GT-R uses brake pad materials that
have high metallic content. The brake pad
material helps maintain braking perfor-
mance in a wide range of weather and driving conditions.
For the first 3,000 - 6,000 miles (5,000 -
10,000 km) of the vehicle’s service life, and
for the first 3,000 - 6,000 miles (5,000 -
10,000 km) after a brake replacement, the
brake pad to brake rotor clearance is very
small. When parking, apply the parking
brake and move the shift lever to the
position. Idle the engine for more than 20
seconds without depressing the brake
pedal. This allows the brake pads to move
away from the rotor so the pad does not
contact the rotor.
Additionally, the brakes must be dry
before parking the vehicle after driving
on wet roads or after washing the vehicle.
If the roads are wet, lightly apply the
brakes for a short distance before parking
the vehicle to dry the brakes. After wash-
ing the vehicle, dry the brakes by driving
on a dry road for a few miles and apply
the brakes normally based on traffic and
road conditions.
The metallic brake pads and brake disc
rotor may rust together when the brakes
are not applied:
.
If the vehicle is not idled for 20
seconds without the brakes applied,
or if the brakes are applied when the
vehicle is shut off, the rotor and pads
can rust together, even when the brake pads are dry.
. If the brakes are wet when the vehicle
is parked and the parking brake is
applied for a long time.
It is recommended you contact a GT-R
certified NISSAN dealer if the brake pads
and brake rotor have rusted together.

. This may cause improper windshield
washer operation. If the nozzle is clogged,
remove any objects with a needle or small
pin
. Be careful not to damage the
nozzle. If the brakes do not operate properly,
have the brakes checked. It is recom-
mended you contact a GT-R certified
NISSAN dealer.
SELF-ADJUSTING BRAKESYour vehicle is equipped with self-adjust-
ing brakes.
The disc-type brakes self-adjust every
time the brake pedal is applied.
HIGH PERFORMANCE BRAKE SYS-
TEM (models without NCCB
(NISSAN Carbon Ceramic Brake)
package)This vehicle is equipped with high perfor-
mance brake pads that provide appro-
priate braking force in a broad range of
driving environments. Due to the material
used for the brake pads, the road wheels
may become more easily covered by
brake dust, however this does not indi-
cate that there is a malfunction.
The GT-R brake pads use material that
contains a lot of iron to maintain steady
braking performance even in high and
low temperatures. However, if the brake
