1997 NISSAN FRONTIER height

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 your NISSAN 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 your NISSAN
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 your NISSAN dealer.

cImproper service for a TEMPORARY
USE ONLY spare tire may result in
serious personal injury. If it is nec-
essary to repair the TEMPORARY
USE ONLY spare tire, contact your
NISSAN dealer.
Changing tires and wheels
When replacing a tire, use the same size,
speed rating and load carrying capacity as
originally equipped. Recommended types
and sizes are shown in ``Wheel/tire size'' in
the ``Technical and consumer information''
section.
WARNING
c
The use of tires other than those
recommended or the mixed use of
tires of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the ride,
braking, handling, ground clearance,
body-to-tire clearance, snow chain
clearance, speedometer calibration,
headlight aim and bumper height.
Some of these effects may lead to
accidents and could result in serious
personal injury.cIf the wheels are changed for any
reason, always replace with wheels
which have the same offset dimen-
sion. Wheels of a different offset
could cause early tire wear, poor ve-
hicle handling characteristics and/or
interference with the brake discs/
drums. Such interference can lead to
decreased braking efficiency and/or
early brake pad/shoe wear.
cDo 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.
4-WHEEL DRIVE MODELS
CAUTION
Always use tires of the same size,
brand, construction (bias, bias-belted
or radial), and tread pattern on all four
wheels. Failure to do so may result in a
circumference difference between tires
on the front and rear axles which will
cause excessive tire wear and may
damage the transmission, transfer
case and differential gears.If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked
and corrected as necessary. Contact your
NISSAN dealer.
CAUTION
ONLY use spare tires specified for each
4-wheel drive model.
Wheel balance
Unbalanced 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 balanc-
ing the front wheels on the vehicle could
lead to transmission damage.
Care of wheels
cWash the wheels when washing the ve-
hicle to maintain their appearance.
cClean the inner side of the wheels when
the wheel is changed or the underside of
the vehicle is washed.
