brake pads NISSAN FRONTIER 1998 D22 / 1.G Owners Manual

4-wheel drive indicator light
This light comes on when the transfer shift
control lever is in the 4H or 4L position.
WARNING
cWhen parking, always make sure the
transfer lever is in the 4H or 4L
position and the parking brake is
applied.
cFailure to engage the transfer lever
in 4H or 4L could result in the vehicle
moving unexpectedly, which in turn
could result in serious personal in-
jury or property damage.
Cruise indicator light (if so
equipped)
This light comes on while the vehicle speed
is controlled by the cruise control system. If
the CRUISE indicator blinks, have the sys-
tem checked by an authorized NISSAN
dealer.
orAnti-lock brake warn-
ing light
If the light comes on while the engine is
running, it may indicate a potential problemwith the anti-lock brake system. Have the
system checked by an authorized NISSAN
dealer.
If an abnormality occurs in the system, the
anti-lock function ceases but the ordinary
brakes continue to operate normally.
If the light comes on while you are driving,
contact an authorized NISSAN dealer for
repair.
Overdrive off indicator light
(if so equipped)
This light comes on when the overdrive
switch is pushed to the OFF position.
Key reminder chime
The chime sounds when the driver's door is
opened and the key is left in the ignition
switch. Take the ignition key when you
leave the vehicle.
Light reminder chime
A chime sounds if the driver's door is
opened with the headlight switch on unless
the ignition key is in the ON position. Turn
the headlight switch off when you leave the
vehicle.
Brake pad wear warning
The disc brake pads have audible wear
warnings. When a brake pad requires re-
placement, it makes a high pitched scraping
sound when the vehicle is in motion whether
or not the brake pedal is depressed. Have
the brakes checked as soon as possible if
the warning sound is heard.
Malfunction indicator light
(MIL)
If the malfunction indicator light comes on
steady or blinks while the engine is running,
it may indicate a potential emission control
problem.
The malfunction indicator light may also
come on steady or blink if the fuel filler cap
has not been closed tightly or if the fuel tank
is nearly empty. Check to make sure the
fuel cap is secure and that you have at least
three gallons of fuel in the fuel tank.
After driving for a while, the light should
remain off if no other potential emission
control system problem exists.
2-10Instruments and controls
ZX

The brake system has two separate hydrau-
lic circuits. If one circuit develops a problem,
you will still have braking at two wheels.
Vacuum assisted brakes
The 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 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 the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal
to heat the brakes. Do this until the brakes
return to normal. Avoid driving the vehicle at
high speeds until the brakes function cor-
rectly.Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake linings and pads faster,
and reduce gas mileage.
To help reduce brake wear, and to prevent
the brakes from overheating, reduce speed
and downshift to a lower gear before going
down a slope or long grade.
WARNING
cWhile driving on a slippery surface,
be careful when braking, accelerat-
ing or downshifting. Abrupt braking
actions or sudden acceleration
could cause the wheels to skid and
result in an accident.
cIf the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.
Normal Operation
The anti-lock brake system does not oper-
ate at speeds below 3 to 6 MPH (5 to 10
km/h). (The speeds vary according to road
conditions.)
When driving, the anti-lock brake system
controls the wheels so they will not lock
when braking abruptly or when braking on a
slippery road. Thus, difficult steering and
swerving of the vehicle due to locked
wheels is minimized. The system detects
the wheel rotation rate and electronically
controls the pressure applied to each brake.
Slight vibration on the brake pedal accom-
panied by noise usually occurs while the
ABS system is operating. Such vibration
and noise encountered during abrupt brak-
ing is not a problem, but indicates that the
system is functioning.
Even with the rear anti-lock brake sys-
tem, your front wheels can still lock. If
this happens, release the brake pedal
slightly and then reapply pressure.
Self-test feature
The anti-lock brake system consists of elec-
tronic sensors and hydraulic solenoids con-
trolled by a computer. The computer has a

Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front disc-type brakes self-adjust every
time the brake pedal is applied. The rear
drum-type brakes on two-wheel drive trucks
self-adjust every time the parking brake is
applied. The rear drum-type brakes on four-
wheel drive trucks self-adjust every time the
brake pedal is applied. If the brake pedal
goes down farther than normal, it may be
due to a lack of adjustment of the rear drum
brakes. Apply the parking brake several
times.
WARNING
If the brake pedal height does not re-
turn to normal, see an authorized NIS-
SAN dealer and have it checked.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, it will make a high
pitched scraping or screeching sound when
the vehicle is in motion whether or not the
brake pedal is depressed. Have the brakeschecked as soon as possible if the wear
indicator sound is heard.
Under some driving or climate conditions,
occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is nor-
mal and does not affect the function or
performance of the brake system.
The rear drum brakes (if so equipped) do
not have audible wear indicators. Should
you ever hear an unusually loud noise from
the rear drum brakes, have them inspected
as soon as possible by an authorized NIS-
SAN dealer.
Proper brake inspection intervals should
be followed.For more information regard-
ing brake inspections, see the appropriate
maintenance schedule information in the
``Maintenance Schedule'' section of this
manual.Check the brake booster function with the
following steps:
1. With the engine off, press and release
the brake pedal several times. When
brake pedal movement (distance of
travel) remains the same from one pedal
application to the next, continue on to
next step.
2. While depressing the brake pedal, start
the engine. The pedal height should drop
a little.
3. With the brake pedal depressed, stop the
engine. Keeping the pedal depressed for
about 30 seconds, the pedal height
should not change.
4. Run the engine for one minute without
depressing the brake pedal, then turn it
off. Depress the brake pedal several
times. The pedal travel distance will de-
crease gradually with each depression
as the vacuum is released from the
booster.
If the brakes do not operate properly, have
the brakes checked by an authorized NIS-
SAN dealer.

To ensure smooth, trouble-free, safe and
economical driving, NISSAN provides two
periodic 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 60,000 miles (96,000 km)/48 months. For
most people, the odometer reading will in-
dicate 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 60,000 miles (96,000 km)/48
months, continue periodic maintenance
at the same mileage/time intervals.
SCHEDULE ONE
Follow Periodic Maintenance Schedule one
if your driving habits frequently include one
or more of the following driving conditions:
cRepeated short trips of less than 5
miles (8 km).
cRepeated short trips of less than 10
miles (16 km) with outside tempera-
tures below freezing.
cOperating the vehicle in hot weatherduring stop-and-go ``rush hour'' traf-
fic.
cExtensive idling and/or low speed
driving for long distances, such as
police, taxi or door-to-door delivery
use.
cDriving in dusty conditions.
cDriving on rough, muddy, or salt
spread roads.
cTowing a trailer, using a camper or a
car-top carrier.
SCHEDULE TWO
Follow Periodic Maintenance Schedule two
if none of the driving conditions shown in
Schedule one apply to your driving habits.
Maintenance for off-road driving
(
only)
Whenever you drive off-road through sand,
mud or water as deep as the wheel hub,
more frequent maintenance may be re-
quired of the following items:
¶Brake pads and rotors
¶Brake linings and drums
¶Brake lines and hoses
¶Wheel bearing grease and free-running
hub grease
¶Differential, transmission and transfer oil
¶Steering linkage
¶Propeller shafts and front drive shafts
¶Air cleaner filter
These items should be checked frequently
to assure safe and proper operation of your
vehicle.

yourself'' section of this manual.
Emission control system
maintenance
Drive belts*Check drive belts for wear,
fraying or cracking and also for proper ten-
sion. Replace any damaged drive belts.
Air cleaner filterUnder normal driving con-
ditions, the air cleaner filter should be re-
placed in accordance with the maintenance
schedule. However, driving the vehicle in
dusty areas may cause rapid clogging of the
element. Consequently, the element may
have to be replaced more frequently.
Positive crankcase ventilation (PCV) fil-
terUnder normal driving conditions, the
filter should be replaced in accordance with
the maintenance schedule. If the vehicle is
operated under extremely adverse weather
conditions or in areas where ambient tem-
peratures are either extremely low or ex-
tremely high, the filter may become cloggedmore rapidly. In such an event, replace the
filter immediately.
EVAP Vapor linesCheck vapor lines and
connections for leaks, looseness, or dete-
rioration. If leaks are found, replace the
lines.
Fuel lines (hoses, piping, connections,
etc.)Check the fuel hoses, piping and con-
nections for leaks, looseness or deteriora-
tion. Replace any damaged parts.
Fuel filterIf the vehicle is operated under
extremely adverse weather conditions or in
areas where ambient temperatures are ei-
ther extremely low or extremely high, the
filter might become clogged. In such an
event, replace the filter immediately.
Engine coolant*Flush and refill the cooling
system.
Engine oil and oil filter*Under normal
driving conditions, the engine oil and oil filter
should be replaced in accordance with the
maintenance schedule. However, under se-
vere driving conditions, they may have to be
replaced more frequently.
Spark plugs*Replace with new plugs hav-
ing the correct heat range.
Chassis and body maintenance
Brake lines and cablesCheck the brake
lines and hoses (including brake booster
vacuum hoses, connections & check valve)
and parking brake cables for proper attach-
ment, leaks, cracks, chafing, abrasion, de-
terioration, etc.
Brake pads, discs, drums and linings
Check these and the other brake compo-
nents for wear, deterioration and leaks. Un-
der severe driving conditions, they may have
to be inspected more frequently.
Manual and automatic transmission,
transfer and differential gear oilVisually
inspect for signs of leakage. Under severe
driving conditions, the oil should be re-
placed at the specified interval.
Steering gear (box) and linkage, axle and
suspension parts and drive shaft boots
Check for damage, looseness and leakage
of oil or grease. Under severe driving con-
ditions, they may have to be inspected more
frequently.
