1998 NISSAN MAXIMA brake

Be sure the engine and ignition switch
are off and that the parking brake is
engaged securely.Be sure to use the correct wrench to
remove the plugs. An incorrect wrench
can cause damage.
REPLACING SPARK PLUGS1. Remove the rocker cover ornament using a
suitable hexagon wrench. (Front side)
2. Disconnect the electrical connectors.
3. Loosen the ignition coil fixing bolts. And
remove the ignition coil to give access to
the spark plugs.
4. Remove the spark plugs with a spark plug
wrench.
The plug wrench has a rubber seal that
holds the spark plug so that it will not fall
when it is pulled out. Make sure that eachspark plug is snugly fitted into the plug
wrench.
5. Fit the new plugs, one at a time, into the
spark plug wrench and install them. Turn
each plug in several full turns by hand, then
tighten with a spark plug wrench to the
correct torque. Do not overtighten.
Spark plug tightening torque:
14 to 22 ft-lb
(20 to 29 N×m)

CHECKING PARKING BRAKEFrom the released position, pull the parking
brake lever up slowly and firmly. If the number
of clicks is out of the range listed above, see
your NISSAN dealer.
CHECKING BRAKE PEDALWith the engine running, check the distance
between the upper surface of the pedal and
the metal floor. If it is out of the range shown
above, see your NISSAN dealer.Self-adjusting brakesYour vehicle is equipped with self-adjusting
brakes.
The disc-type brakes self-adjust every time the
brake pedal is applied.
See your NISSAN dealer and have it
checked if the brake pedal height does
not return to normal.Brake pad wear indicatorsThe 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 brakes
checked as soon as possible if the wear indi-
cator sound is heard.
Under some driving or climate conditions, oc-
casional brake squeak, squeal or other noise
may be heard. Occasional brake noise during
light to moderate stops is normal and does not
affect the function or performance of the brake
system.
Proper brake inspection intervals should
be followed.For additional information, see
ªPeriodic maintenance schedulesº in the ª9.
Maintenanceº section for maintenance inter-
vals.

BRAKE BOOSTERCheck the brake booster function as follows:
1. With the engine off, press and release the
brake pedal several times. When brake
pedal movement (distance of travel) re-
mains the same from one pedal application
to the next, continue on to the 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 decrease gradu-
ally with each depression as the vacuum is
released from the booster.
If the brakes do not operate properly, see your
NISSAN dealer.Press the pedal by hand and be sure the free
travel is within the limits shown above. If free
travel is too little or too much, see your
NISSAN dealer.
Never use a fuse of higher amperage
rating than that specified on the fuse
box cover. This could damage the elec-
trical system or cause a fire.

which have the same offset dimen-
sion. Wheels of a different offset
could cause early tire wear, possibly
degraded vehicle handling character-
istics and/or interference with the
brake discs. Such interference can
lead to decreased braking efficiency
and/or early brake pad wear.
IDo not install a deformed wheel or
tire even if it has been repaired. Such
wheels or tires could have structural
damage and could fail without warn-
ing.
IThe use of retread tire is not
recommended.
Wheel balanceUnbalanced wheels may affect vehicle han-
dling and tire life. Even with regular use,
wheels can get out of balance. Therefore, they
should be balanced as required.
Wheel balance service should be performed
with the wheels off the vehicle. Spin balancing
the front wheels on the vehicle could lead to
transmission damage.
Care of wheelsIWash the wheels when washing the vehicle
to maintain their appearance.
IClean the inner side of the wheels when the
wheel is changed or the underside of the
vehicle is washed.
IDo not use abrasive cleaners when wash-
ing the wheels.
IInspect wheel rims regularly for dents or
corrosion. Such damage may cause loss of
pressure or poor seal at the tire bead.
INISSAN recommends that the road wheels
be waxed to protect against road salt in
areas where it is used during winter.Spare tire (T-type spare tire)Observe the following precautions if the T-type
spare tire must be used, otherwise your ve-
hicle could be damaged or involved in an
accident.
IThe T-type spare tire should be used
only for emergency. It should be re-
placed by the standard tire at the first
opportunity.
IDrive carefully while the T-type spare
tire is installed.
Avoid sharp turns and abrupt braking
while driving.
IPeriodically check tire inflation pres-
sure, and always keep it at 60 psi (420
kPa, 4.2 bar).
IDo not drive your vehicle at speeds
faster than 50 MPH (80 km/h).
IDo not use tire chains on a T-type
spare tire. Tire chains will not fit prop-
erly on the T-type spare tire and may
cause damage to the vehicle.
IWhen driving on roads covered with
snow or ice, the T-type spare tire
should be used on the rear wheel and
the original tire used on the front
wheels (drive wheels). Use tire chains
only on the front two original tires.

ing or cracking and also for proper tension.
Replace the drive belts if found damaged.
Air cleaner filter:Under normal driving con-
ditions, the air cleaner filter should be replaced
in accordance with the maintenance schedule.
However, driving the vehicle in dusty areas
may cause more rapid clogging of the element.
Consequently, the element may have to be
replaced more frequently.
EVAP vapor lines:Check EVAP vapor lines
and connections for failure or looseness. If
leaks are found, replace them.
Fuel lines:Check the fuel hoses, piping and
connections for leaks, looseness or deteriora-
tion. Replace any parts if they are damaged.Fuel filter:If the vehicle is operated under
extremely adverse weather conditions or in
areas where ambient temperatures are either
extremely low or extremely high, the filter
might become clogged. In such an event,
replace the filter immediately.
Engine coolant*:Drain and flush the cooling
system.
Engine oil & oil filter*:Under normal driving
conditions, the engine oil and oil filter should
be replaced in accordance with the mainte-
nance schedule. However, under severe driv-
ing conditions, they may have to be replaced
more frequently.
Spark plugs*:Replace with new plugs having
the correct heat range.
Intake & exhaust valve clearance:Check the
valve clearance if valve noise increases.
Chassis and body maintenanceBrake lines & cables:Check the brake lines
and hoses (including brake booster vacuum
hoses, connections & check valve) and park-
ing brake cables for proper attachment, leaks,
cracks, chafing, abrasion, deterioration, etc.Brake pads & discs:Check these and the
other neighboring brake components for wear,
deterioration and leaks. Under severe driving
