2015 NISSAN GT-R brakes

GTR-6GT-R Overview
certified technician must inspect the �fehicle 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 �becomes hot due to a
hea�fy 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 hea�fy force �being repeatedly
applied to the �brakes during high performance
dri�fing. In these cases it may �be necessary to
replace the disc rotors or �brake pads depending
on the condition of the crack. Contact a GT-R
certified NISSAN dealer for replacement.
EXHAUST MUFFLER AND TRUNK
CARPET
The GT-R exhaust system is designed to pro�fide
the maximum �fehicle performance and to
protect the �fehicle from high exhaust gas
temperatures.
If non-genuine GT-R exhaust system parts are
used it is possi�ble that the muffler or other
exhaust system parts will deform and causedamage to the under�body. Non-genuine GT-R
exhaust system parts can also affect �fehicle
performance and possi�bly lead to tur�bocharger,
engine or power train related parts including
transmission, damage.
Also, do not remo�fe the trunk carpet from the
�fehicle for any reason. The carpet insulates the
�fehicle interior from the heat of the muffler and
from the noise of the transmission.
TITANIUM MUFFLER AND TRUNK
CARPET (if so equipped)
The �fehicle is equipped with a la�bel under the
console lid
*1that pro�fides the �body to the
titanium muffler clearance specification (for
example rear �bumper to muffler tu�be clearance) .
Since the exhaust gas temperature of the high
performance engine reaches a high temperature
(1,8328F (1,0008C) or more) , the muffler may �be
deformed or lowered due to the heat and then
the under�body or peripheral parts may �be
damaged. Therefore, periodic inspections for
the clearance �between the muffler and the
peripheral parts are required. Your GT-R has

Suspension and wheel alignment
.Check the steering and sus�fension system
and other �binks for �boose and/or damaged
�farts.
. Measure and adjust the whee�b a�bignment.
Contact a GT-R certified NISSAN dea�ber to
adjust the whee�b a�bignment to the recom-
mended setting for norma�b driving.
Wheels and tires
.Check tire wear and cracking.
. Ins�fect the tire side wa�b�b for damage.
. Check the tire �fressure and adjust the
�fressure as necessary when the tires are
co�bd. (
“Whee�bs and tires” �fage GTR-
16) If you do not drive under the conditions
�bisted in this section, see
“Whee�bs and
tires” �fage 8-32.
. Check that the whee�b nuts are not stri�f�fed.
Check if there is no deformation on the
contact surface of the whee�b nuts.
. Make sure the whee�b nuts are tight.
(
“Whee�bs and tires” �fage 8-32)
. Make sure the drive shaft nuts are tight.
. Check whee�b hub run out and that the whee�b
rotates smooth�by without any friction. Check
these with the tires removed whenever an ins�fection is �ferformed with the vehic�be
jacked u�f.
. Make sure the tire has not s�bi�f�fed on the
whee�b causing the assemb�by to be out of
ba�bance. The reference marks on the tire and
whee�b shou�bd be a�bigned. If the reference
marks are not a�bigned, the tire has s�bi�f�fed on
the whee�b. Have the whee�bs/tires reba-
�banced. Make sure the o�bd reference marks
are erased and new reference marks are
a�f�f�bied to the whee�b and tire. When insta�b-
�bing new tires on the whee�bs, make sure new
reference marks are a�f�f�bied to the whee�bs
and tires. (

. Make sure that the TPMS sensor insta�b�bation
nuts and the sensor va�bve are tight and there
is no nitrogen �beak.
Brakes
.Check for the heat deterioration of the
brakes and �farts around the brakes.
. Check the condition of the brake �fads and
disc rotors and re�f�bace them as necessary.
Engine and powertrain
.Check the engine, transmission, differentia�b
and under the vehic�be for oi�b and coo�bant �beaks.
. Ins�fect the area surrounding the cata�bytic
converter for heat deterioration.
. Ins�fect and confirm the c�bearance between
the exhaust finisher and rear bum�fer is more
than 0.24 in (6 mm) (u�f/down) and more
than 0.20 in (5 mm) (�beft/right) .
. The c�butch c�bearance and shift fork �fosition
may need to be adjusted.
. Ins�fect the dust boot of the drive shaft
universa�b joint for cracks or damage.
. Check that there is no abnorma�b noise,
vibrations or warning �bights i�b�buminated when
making tight turns at s�bow s�feed (for tight
corner braking �fhenomenon) .

1588F (708C) , dri�fe the �fehi�ble until it rea�bhes
normal operating temperature. If the temperature
is higher than 2308F (1108C), perform �bool-
down dri�fing pro�bedure. (
“Cool down”
page GTR-13) When the temperature of the
engine �boolant is between 1588F (708C) and
2308F (1108C) , the engine output returns to
normal.
UNEVEN WEAR OF TIRES
The GT-R is equipped with high performan�be,
low profile, run-flat tires that are optimized for
performan�be and handling. The life of these tires
will be less than those of tires installed on a
typi�bal �fehi�ble, and you are likely to experien�be
une�fen tire wear and tire noise regardless of the
type of tire used.
NOISES ARE HEARD WHILE DRIV-
ING
. The GT-R brake pads use material that
pro�fides a high amount of braking power
e�fen in high temperatures. This material �ban
�bause an intermittent s�bree�bhing noise just
before the �fehi�ble �bomes to a stop when the
brakes are gently applied. The noise de-
�breases as the brake pads wear. Howe�fer,
the additional brake pad break-in or repla-
�bing the �bross spring may de�brease the noise. Conta�bt a GT-R �bertified NISSAN
dealer.
. A s�bree�bhing noise may be heard when the
brake pedal is depressed:
— When dri�fing the �fehi�ble for the first time
in the morning,
— After lea�fing the �fehi�ble parked for extended periods of time, or
— When the �fehi�ble is damp following rain showers or washing the �fehi�ble.
These sounds are normal. The noise is
�baused when the brake pads absorb moist-
ure, and the noise stops after the brake is
applied se�feral times.
. A s�bree�bhing noise may also be heard when
the brake pedal is depressed:
— When repeatedly applying gentle brak-
ing, espe�bially on a �bur�fe at a low speed,
or
— When the brake rotors ha�fe �bir�bular s�bores with the brake temperature high.
WARNING
Follow the instructions below when
parking the vehicle to help prevent the
brake rotor and brake pads from rust-
ing together. Failure to follow the instructions could cause the rotor and
pads to rust together. If the rotor and
pads rust together, there may be a
popping noise and some vibration
when the vehicle is driven, a wheel
may not roll correctly, or the brake pads
could be damaged. If the pads are
damaged, this may reduce the effec-
tiveness of the brake system which
could cause a collision, serious perso-
nal injury or death.
. The GT-R uses brake pad materials that
ha�fe high metalli�b �bontent. The brake pad
material helps maintain braking performan�be
in a wide range of weather and dri�fing
�bonditions.
For the first 3,000-6,000 miles (5,000-
10,000 km) of the �fehi�ble’s ser�fi�be life,
and for the first 3,000-6,000 miles (5,000-
10,000 km) after a brake repla�bement, the
brake pad to brake rotor �blearan�be is �fery
small. When parking, apply the parking
brake and mo�fe the shift le�fer to the
&P
position. Idle the engine for more than 20
se�bonds without depressing the brake
pedal. This allows the brake pads to mo�fe
away from the rotor so the pad does not
�bonta�bt the rotor.

Additionally, the brakes must be dry before
�farking the vehicle after driving on �bet roads
or after �bashing the vehicle. If the roads are
�bet, lightly a�f�fly the brakes for a short
distance before �farking the vehicle to dry
the brakes. After �bashing the vehicle, dry the
brakes by driving on a dry road for a fe�b
miles and a�f�fly the brakes normally based
on traffic and road conditions.
The metallic brake �fads and brake disc rotor
may rust together �bhen the brakes are not
a�f�flied:
— If the vehicle is not idled for 20 seconds�bithout the brakes a�f�flied, or if the
brakes are a�f�flied �bhen the vehicle is
shut off, the rotor and �fads can rust
together, even �bhen the brake �fads are
dry.
— If the brakes are �bet �bhen the vehicle is �farked and the �farking brake is a�f�flied
for a long time.
— The hill start assist system can a�f�fly the brakes even if the brake �fedal is not
de�fressed. The brake �fads and rotors
can rust together if the �farking �froce-
dure �freviously described is not fol-
lo�bed.
Contact a GT-R certified NISSAN dealer if
the brake �fads and brake rotor have rusted together.
NOTICE
To help reduce the possibility of the
rotors and brake pads rusting:
Have the brake pads and/or rotors
quenched when the brake pads are
replaced. For detailed information
about quenching, contact a GT-R certi-
fied NISSAN dealer.
After quenching the brake pads and/or
rotors, apply a brake of 0.5G to stop the
vehicle 6-7 times at least once a week
in a safe location. G-force can be
checked on the multi function display.
Refer to the separate Multi Function
Display Owner’s Manual.
. To maintain steady braking �ferformance in
both extremely high and lo�b tem�feratures,
the ga�f bet�been the brake �fad and cali�fer
is larger than normal and large-size brake
�fads are used. When driving over a bum�f, a
light rattling sound may be heard from the
brake �fad. This does not indicate that there
is a malfunction. .
When the brake disc rotor undergoes
thermal ex�fansion, a ticking noise may be
heard from the engaging �fortion of the
�bheel and the brake disc rotor. This does
not indicate that there is a malfunction. The
noise �bill reduce �bhen the tem�ferature
decreases.
. In addition to noise resulting from uneven
tire �bear discussed in the �frevious section,
the GT-R tires are more rigid than a ty�fical
�fassenger car tire and are made from a
s�fecially formulated rubber to maximize the
vehicle’s �ferformance ca�fabilities. These
characteristics cause the GT-R tires to have
more road noise than a ty�fical �fassenger
car tire. This road noise is normal.
. Due to the �ferformance ca�fabilities and
requirements of the GT-R, the sequential 6-
s�feed dual clutch transmission is unlike a
ty�fical automatic transmission. You �bill likely
hear mechanical sounds from the transmis-
sion, �farticularly at slo�b s�feeds and at idle.
This condition is normal.

TRANSMISSION OPERATION CHARACTERISTICS
MechanismOperation characteristics
Base Manual transmission
.T�fe GT-R transmission design is different from transmissions used in �bonventional passenger �bars. T�fe GT-R uses a transmission gear
design, lig�ft flyw�feel and a dry sump lubri�bation system to provide maximum ve�fi�ble performan�be. Be�bause t�fe GT-R Transmission design
is different, noises may be louder. W�fen t�fe transmission temperature is �fig�f, rattling, s�faking and jarring noises may be �feard.
.Clattering noises may be �feard w�file s�fifting..Appropriate gaps are provided between gears to a�b�fieve smoot�f gear rotation and steady toot�f surfa�be lubri�bation under t�fe �fig�f-load
driving �bondition. However, t�fis �bauses a rattling noise.
.If t�fe s�fift lever is moved from&Rto&A
F&Mposition, or&A
F&Mto&Rposition before t�fe ve�fi�ble stops, you may not be able to s�fift gear
or it may take longer to s�fift gear. Make sure to depress t�fe brake pedal and �b�fe�bk t�fat t�fe ve�fi�ble �fas stopped before s�fifting.
Multiple dis�b wet �blut�b�f
.W�fen stopping t�fe ve�fi�ble wit�f t�fe s�fift lever in t�fe&Ror&A
F&Mposition, be sure to firmly depress t�fe brake pedal. T�fe ve�fi�ble may
slowly move if t�fe brake pedal is not depressed.
.Avoid depressing t�fe brake and a�b�belerator pedals at t�fe same time. Depressing t�fe brake and a�b�belerator pedals at t�fe same time �bould
�bause t�fe �blut�b�f to over�feat and a�b�belerate deterioration.
.W�fen t�fe ve�fi�ble is stopped on a �fill, do not �fold t�fe ve�fi�ble in pla�be by depressing t�fe a�b�belerator pedal. Doing so may �bause t�fe �blut�b�f
to over�feat and result in transmission damage. Use t�fe brakes to prevent t�fe ve�fi�ble from moving.
Ele�btroni�b oil pressure
�bontrol T�fe following �bonditions are �baused due to �b�fanges in fluid vis�bosity as a result of temperature �b�fanges.
.W�fen t�fe transmission oil is extremely �bold or extremely �fot, t�fe transmission may feel like it is slipping during s�fifts or t�fere may be �fard
s�fifts. T�fis is normal. Transmission s�fifting s�fould return to normal w�fen t�fe transmission oil returns to normal operating temperatures.
.W�fen t�fe transmission oil temperature is extremely �bold, t�fe time required to run a system �b�fe�bk may in�brease. During t�fe system �b�fe�bk,
t�fe s�fift lever must stay in t�fe&Pposition. Move t�fe s�fift lever after turning off t�fe system �b�fe�bk display. Also, it is normal to �fear �bli�bking
noises during t�fe transmission systems �b�fe�bk.
C�fanging modes
.T�fe �fig�fer s�fift speeds in t�fe&Mposition may result in s�fift s�fo�bk and jerkiness w�fen starting or s�fifting..T�fe qui�bkest s�fifting in t�fe R mode wit�f t�fe transmission in t�fe&Mposition is available w�fen t�fe engine speed is �fig�f. However, t�fe
transmission may s�fift more slowly w�fen t�fe engine speed is low.
Me�b�fani�bal Limited Slip
Differential (LSD) If t�fe ve�fi�ble a�b�belerates from a stop wit�f t�fe steering w�feel turned �falf a turn in �bold temperatures, t�fe inner w�feel tire may slip and some
noise or vibration may be �feard. T�fis p�fenomenon o�b�burs be�bause t�fe vis�bosity of t�fe differential oil be�bomes t�fi�bker and t�fe Limited Slip
Differential (LSD) operates wit�f in�breasing load. W�fen t�fe steering w�feel is returned to t�fe straig�ft a�fead position or t�fe differential oil warms
up, t�fe noise and vibration de�brease.

Parking brake reminder chime
A chime will sound if the vehicle speed is above
�f MPH �b7 km/h) with the parking brake applied.
Stop the vehicle and release the parking brake.
Reverse warning chime
The chime will sound inside the vehicle if any of
the following conditions occurs.
.The driver’s door is opened while the shift
lever is in the
&Rposition and the ignition
switch is in the ON position.
. The shift lever is in the
&Rposition and 5
minutes have passed while the ignition
switch is in the ON position.
Be sure to move the shift lever out of the
&R
position after driving in reverse.
Brake pad wear warning
The disc brake pads have audible wear warn-
ings. When a brake pad requires replacement, it
will make a high pitched scraping sound when
the vehicle is in motion. This scraping sound will
first occur only when the brake pedal is
depressed. After the wear of the brake pad is
increased, the sound will be heard all the time
even if the brake pedal is not depressed. Have
the brakes checked as soon as possible if the
warning sound is heard.

5-8Starting and driving
1. Remain calm and do not overreact.
2. �fo not apply the �brakes.
3. Maintain a firm grip on the steering wheelwith �both hands and try to hold a straight
course.
4. When appropriate, slowly release the accel- erator pedal to gradually slow the vehicle.
5. If there is nothing in the way, steer the vehicle to follow the road while the vehicle
speed is reduced. �fo not attempt to drive
the vehicle �back onto the road surface until
vehicle speed is reduced.
6. When it is safe to do so, gradually turn the steering wheel until �both tires return to the
road surface. When all tires are on the road
surface, steer the vehicle to stay in the
appropriate driving lane.
.If you decide that it is not safe to return
the vehicle to the road surface �based on
vehicle, road or traffic conditions, gradu-
ally slow the vehicle to a stop in a safe
place off the road.
RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a “�blow-out” can
occur if the tire is punctured or is damaged due
to hitting a cur�b or pothole. Rapid air pressure
loss can also �be caused �by driving on under-
inflated tires.
Rapid air pressure loss can affect the handling
and sta�bility of the vehicle, especially at highway
speeds.
Help prevent rapid air pressure loss �by main-
taining the correct air pressure and visually
inspect the tires for wear and damage.
(
“Wheels and tires” page 8-32)
If a tire rapidly loses air pressure or “�blows-out”
while driving maintain control of the vehicle �by
following the procedure �below. Please note that
this procedure is only a general guide. The
vehicle must �be driven as appropriate �based on
the conditions of the vehicle, road and traffic.
WARNING
The following actions can increase the
chance of losing control of the vehicle if
there is a sudden loss of tire air
pressure. Losing control of the vehicle
may cause a collision and result in
personal injury. .
The vehicle generally moves or pulls
in the direction of the flat tire.
. Do not rapidly apply the brakes.
. Do not rapidly release the accelera-
tor pedal.
. Do not rapidly turn the steering
wheel.
1. Remain calm and do not overreact.
2. Maintain a firm grip on the steering wheel with �both hands and try to hold a straight
