brake rotor INFINITI QX80 2023 Owners Manual

BRAKING PRECAUTIONS
The brake system has two separate hydrau-
lic circuits. If one circuit malfunctions, you
will still have braking ability at two wheels.
You may feel a small click and hear a sound
when the brake pedal is fully depressed
slowly. This is not a malfunction and in-
dicates that the brake assist mechanism is
operating properly.
Hydraulically-assisted brakes
The hydraulically-assisted brake system is
designed to use a hydraulic pump driven
electrically, to assist braking. If the engine
stops, you can stop the vehicle by depressing
the foot brake pedal. However, greater foot
pressure on the foot brake pedal will be
required to stop the vehicle. The stopping
distance will be longer.
Wet brakes
When 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 tapping 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 brakesfunction correctly.
PARKING BRAKE BREAK-IN
Break in the parking brake shoes whenever
the stopping 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 perfor-
mance.
This procedure is described in the vehicle
service manual. It is recommended you visit
an INFINITI retailer for this service.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will cause overheating of
the brakes, wearing out the brake and pads
faster and reduce 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, accelerating
or downshifting. Abrupt braking or
accelerating could cause the wheels to skid and result in an accident.
. 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.
Starting and driving5-133
BRAKE SYSTEM

5-136Starting and driving
The computer has a built-in diagnostic
feature that tests the system each time you
start the engine and move the vehicle
forward or in reverse at a slow speed. 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
by careless or dangerous driving
techniques. Reduce vehicle speed
and be especially careful when driving
and cornering on slippery surfaces
and always drive carefully.
. Do not modify the vehicle’s suspen-
sion. If suspension parts such as
shock absorbers, struts, springs, sta-
bilizer bars, bushings and wheels are
not INFINITI recommended for your
vehicle or are extremely deteriorated,
the VDC system may not operate
properly. This could adversely affect
vehicle handling performance, and
the VDC warning light
may
illuminate. .
If brake related parts such as brake
pads, rotors and calipers are not
INFINITI recommended or are extre-
mely deteriorated, the VDC system
may not operate properly and the
VDC warning light
may illumi-
nate.
. If engine control related parts are not
INFINITI recommended or are extre-
mely deteriorated, the VDC warning
light
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 warning
light
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 warning light
may
illuminate. This is not a malfunction.
Restart the engine after driving onto
a stable surface.
. If wheels or tires other than the
INFINITI recommended ones are
used, the VDC system may not oper-
ate properly and the VDC warning
light
may illuminate.
. The VDC system is not a substitute
for winter tires or tire chains on a snow covered road.

9-6Maintenance and schedules
Brake pads and rotors:
Check for wear, deterioration and fluid
leaks. Replace any deteriorated or damaged
parts immediately.
Exhaust system:
Visually inspect the exhaust pipes, muffler
and hangers for leaks, cracks, deterioration,
and damage. Tighten connections or replace
parts as necessary.
In-cabin microfilter:
Replace at specified intervals. When driving
for prolonged periods in dusty conditions,
replace the filter more frequently.
Propeller shaft(s):
Check for damage, looseness, and grease
leakage. (4WD/RWD)
Steering gear and linkage, axle and suspen-
sion parts, drive shaft boots:
Check for damage, looseness, and leakage
of oil or grease. Under severe driving condi-
tions, inspect more frequently.
Tire rotation:
Rotate tires at the specified interval. When
rotating tires, check for damage and uneven
wear. Replace if necessary.
Differential oil and transfer case oil:
Visually inspect for signs of leakage at
specified intervals.To help ensure smooth, safe and economical
driving, INFINITI provides two maintenance
schedules that may be used, depending upon
the conditions in which you usually drive.
These schedules contain both distance and
time intervals, up to 120,000 miles
(192,000 km)/96 months. For most people,
the odometer reading will indicate when
service is needed. However, if you drive very
little, your vehicle should be serviced at the
regular time intervals shown in the schedule.
After 120,000 miles (192,000 km)/96
months, continue maintenance at the same
mileage/time intervals.
ADDITIONAL MAINTENANCE
ITEMS FOR SEVERE OPERATING
CONDITIONS
Additional maintenance items for severe
operating conditions;should be performed
on vehicles that are driven under especially
demanding conditions. Additional mainte-
nance items should be performed if you
primarily operate your vehicle under the
following conditions:
. Repeated short trips of less than 5 miles
(8 km).
. Repeated short trips of less than 10 miles
(16 km) with outside temperatures re-
maining below freezing. .
Operating in hot weather in stop-and-go
“rush hour” traffic.
. Extensive idling and/or low speed driving
for long distances, such as police, taxi or
door-to-door delivery use.
. Driving in dusty conditions.
. Driving on rough, muddy or salt spread
roads.
. Towing a trailer, using a camper or car-
top carrier.
If your vehicle is mainly operated under the
severe conditions, follow the severe use
maintenance intervals shown in the main-
tenance schedule.
