brake rotor NISSAN 350Z 2008 Z33 Owners Manual

BRAKING PRECAUTIONSThe brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.Vacuum assisted brakesThe brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and the stopping
distance will be longer.Using the brakesAvoid resting your foot on the brake pedal while
driving. This overheats the brakes, increases
wear on the brakes and pads, and reduces gas
mileage.
To help save the brakes and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
WARNING

While driving on a slippery surface,
be careful when braking, accelerat-
ing or downshifting. Abrupt braking
or accelerating could cause the
wheels to skid and result in an acci-
dent.

If the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.Wet brakesWhen the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry brakes, drive the vehicle at a safe speed
while lightly pressing the brake pedal to heat-up
the brakes. Do this until the brakes return to
normal. Avoid driving the vehicle at high speeds
until the brakes function correctly.Parking brake break-inBreak in the parking brake shoes whenever thestopping effect of the parking brake is weakened
or whenever the parking brake shoes and/or
drums/rotors are replaced, in order to assure the
best braking performance.
This procedure is described in the vehicle ser-
vice manual and can be performed by a NISSAN
dealer.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING

The Anti-lock Braking System (ABS)
is a sophisticated device, but it can-
not prevent accidents resulting from
careless or dangerous driving tech-
niques. It can help maintain vehicle
control during braking on slippery
surfaces. Remember that stopping
distances on slippery surfaces will be
longer than on normal surfaces even
with ABS. Stopping distances may
also be longer on rough, gravel or
snow covered roads, or if you are
using tire chains. Always maintain a
safe distance from the vehicle in

system turned off, all VDC system functions will
be turned off. The ABLS system and ABS will
still operate with the VDC system off. When the
ABLS system is activated, the “SLIP” indicator
light will blink and you may hear a clunk noise
and/or feel a pulsation in the brake pedal. This is
normal and is not an indication of a malfunction.
While the VDC system is operating, you may feel
a pulsation in the brake pedal and hear a noise or
feel a vibration from under the hood. This is
normal and indicates that the VDC system is
working properly.
The VDC system computer has a built-in diag-
nostic feature that tests the system each time
you start the engine and move the vehicle at a
low speed forward or backward. When the
self-test occurs, you may hear a clunk noise
and/or feel a pulsation in the brake pedal. This is
normal and is not an indication of a malfunction.
WARNING

The VDC system is designed to help
improve driving stability but does not
prevent accidents due to abrupt
steering operation at high speeds or
due to careless or dangerous drivingtechniques. Reduce vehicle speed
and be especially careful when driv-
ing and cornering on slippery sur-
faces and always drive carefully.

Do not modify the vehicle’s suspen-
sion. If suspension parts such as
shock absorbers, struts, springs, sta-
bilizer bars and bushings and wheels
are not NISSAN-approved or are ex-
tremely deteriorated the VDC system
may not operate properly. This could
adversely affect vehicle handling per-
formance, and the “VDC OFF” indica-
tor or “SLIP” indicator or both indica-
tor lights may illuminate.

If brake related parts such as brake
pads, rotors and calipers are not
standard equipment or are extremely
deteriorated, the “VDC OFF” indica-
tor or “SLIP” indicator or both indica-
tor lights may illuminate.

If engine related parts such as a muf-
fler are not standard equipment or
are extremely deteriorated, the “VDC
OFF” indicator or “SLIP” indicator orboth indicator lights may illuminate.

When driving on extremely inclined
surfaces such as higher banked cor-
ners, the VDC system may not oper-
ate properly and the “VDC OFF” indi-
cator or “SLIP” indicator or both
indicator lights may illuminate. Do
not drive on these types of roads.

When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the “VDC OFF” indicator or
“SLIP” indicator or both indicator
lights may illuminate. This is not a
malfunction. Restart the engine after
driving onto a stable surface.

If wheels or tires other than those
recommended are used, the VDC sys-
tem may not operate properly and the
“VDC OFF” indicator or “SLIP” indi-
cator or both indicator lights may
illuminate.

The VDC system is not a substitute
for winter tires or tire chains on a
snow-covered road.5-24

Installing the spare tireThe spare tire is designed for emergency
use. See specific instructions under the
heading “Wheels and tires” in the “8. Main-
tenance and do-it-yourself” section.
1. Clean any mud or dirt from the surface
between the wheel and hub.
2. Carefully put the wheel on and tighten the
wheel nuts finger tight. When replacing a
front tire, make sure the hole in the spare tire
wheel is aligned with the pin on the brake
rotor.
3. With the wheel nut wrench, tighten wheelnuts alternately and evenly in the sequence
illustrated (
1
-5) until they are tight.
4. Lower the vehicle slowly until the tire touches
the ground. Then, with the wheel nut wrench,
tighten the wheel nuts securely in the se-
quence as illustrated. Lower the vehicle com-
pletely.
WARNING

Incorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.

Do not use oil or grease on the wheel
studs or nuts. This could cause the
nuts to become loose.

Retighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
As soon as possible tighten the wheel nuts
to the specified torque with a torque
wrench.Wheel nut tightening torque:
80 ft-lb (108 N⋅m)
The wheel nuts must be kept tightened to
specification at all times. It is recom-
mended that wheel nuts be tightened to
specification at each lubrication interval.
Adjust tire pressure to the COLD pressure.
COLD pressure:
After vehicle has been parked for three
hours or more or driven less than 1 mile
(1.6 km).
COLD tire pressures are shown on the Tire
and Loading Information label affixed to
the driver’s side center pillar.
Stowing the damaged tire and toolsSecurely store the spare tire and jacking equip-
ment in the vehicle.
WARNING

Always make sure that the spare tire
and jacking equipment are properly
secured after use. Such items can
become dangerous projectiles in an

TIRE CHAINS
CAUTION
Tire chains/cables should not be in-
stalled on 265/35R19 size tires. Installa-
tion of the tire chains/cables on
265/35R19 size tires will cause damage
to the vehicle. If you plan to use tire
chains/cables, you should install
245/45R18 size tires on your vehicle.
Use of tire chains may be prohibited according
to location. Check the local laws before installing
tire chains. When installing tire chains, make
sure they are of proper size for the tires on your
vehicle and are installed according to the chain
manufacturer’s suggestions.Use only SAE
class “S” chains.Class “S” chains are used on
vehicles with restricted tire to vehicle clearance.
Vehicles that can use Class “S” chains are
designed to meet the SAE standard minimum
clearances between the tire and the closest
vehicle suspension or body component required
to accommodate the use of a winter traction
device (tire chains or cables). The minimum
clearances are determined using the factory
equipped tire size. Other types may damage
your vehicle. Use chain tensioners when recom-mended by the tire chain manufacturer to ensure
a tight fit. Loose end links of the tire chain must
be secured or removed to prevent the possibility
of whipping action damage to the fenders or
undercarriage. If possible, avoid fully loading
your vehicle when using tire chains. In addition,
drive at a reduced speed. Otherwise, your ve-
hicle may be damaged and/or vehicle handling
and performance may be adversely affected.

Never install the tire chains on a T-type
spare tire.

Do not use the tire chains on dry roads.

Tire chains must be installed only on the
rear wheels and not on the front wheels.
CHANGING WHEELS AND TIRES
Tire rotationTires cannot be rotated in this vehicle, as
front tires are different size from rear tires
and the direction of wheel rotation is fixed
in each tire.
A pin is on the front brake rotor to prevent
the rear wheels from being installed in
place of the front wheels. The spare tire
can be installed in place of the front and
rear wheels. When installing the spare
tire in the front wheel, the hole in the
spare tire wheel must be aligned with the
pin on the brake rotor.
WARNING

Retighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
