brake pads NISSAN SENTRA 1996 B14 / 4.G Owners Manual

WARNING
cIf you judge it to be safe, drive care-
fully to the nearest service station for
repairs. Otherwise, have your vehicle
towed because driving it could be
dangerous.
cPressing the brake pedal with the
engine stopped and/or low brake
fluid level may increase your stop-
ping distance and braking will require
greater pedal effort as well as pedal
travel.
orAnti-lock brake
warning light
(If so equipped)
If the light comes on while the engine is
running, it may indicate something wrong
with the anti-lock portion of the brake sys-
tem. Have the system checked by your
Nissan dealer.
Turn off the engine, and start it again by
slowly turning the ignition key (quickly
doing so may cause the ABS light to stay
on when there is nothing wrong). If the
light stays on, have the system checkedby your NISSAN dealer.
If an abnormality occurs in the system, the
anti-lock function ceases, but the regular
braking system continues to operate.
If the light comes on while you are driv-
ing, contact your NISSAN dealer for re-
pair.
O/D OFFOverdrive off indicator light
(Automatic transmission
models only)
This light comes on when the overdrive
switch is pushed to the OFF
position.
Turn signal/hazard indicator
lights
The appropriate light flashes when the turn
signal lever switch is activated.
Both lights flash when the hazard switch is
turned on.
High beam indicator light
This blue light comes on when the headlight
high beam is on and goes out when the low
beam is selected.
Cruise indicator light
(If so equipped)
The light comes on while the vehicle speed
is controlled by the cruise control system.
Key reminder chime
A chime sounds if the driver side door is
opened while the key is left in the ignition
switch. Remove the key and take it with you
when leaving the vehicle.
Light reminder chime
A chime sounds when the driver side door is
opened if the headlights or parking lights
are on (ignition switch is turned off).
Turn the headlight control switch off before
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 de-
pressed. Have the brakes checked as soon
as possible if the warning sound is heard.

cDriving with 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 pres-
sure on the brake pedal will be required
to stop the vehicle and the stopping
distance will be longer.
cDriving with the power assisted steer-
ing:
The power assisted steering is designed
to use a hydraulic pump, driven by the
engine, to assist steering.
If the engine stops or the drive belt
breaks, you will still have control of the
vehicle. However, much greater steering
effort is needed, especially in sharp turns
or at low speeds.
cWet 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 pressing the brakepedal 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.
cAvoid 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.
cTo 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.
cWhile driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking actions or
sudden acceleration could cause the
wheels to skid.The anti-lock brake system controls the
brakes at each wheel so the wheels do not
lock when braking abruptly or when braking
on slippery surfaces. The system detects
the rotation speed at each wheel and varies
the brake fluid pressure to prevent each
wheel from locking and sliding. By prevent-
ing wheel lockup, the system helps the
driver maintain steering control and helps to
minimize swerving and spinning on slippery
surfaces.
Using the system
Depress the brake pedal and hold it down.
It is not necessary to pump the brake
pedal.
Doing so may result in increased stopping
distances.
Normal operation
The anti-lock brake system does not oper-
ate at speeds below 3 to 6 MPH (5 to 10
km/h) to completely stop the vehicle. (The
speeds vary according to road conditions.)
When the anti-lock system senses that one
or more wheels are close to locking up, the
actuator (under the hood) rapidly applies
and releases hydraulic pressure (like pump-
ing the brakes very quickly). While the ac-

normal, it may be due to a lack of adjust-
ment of the rear drum brakes. Apply the
parking brake several times.
WARNING
See your NISSAN dealer and have it
checked if the brake pedal height does
not return to normal.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, it makes 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
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 fromthe 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 as fol-
lows:
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 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 de-
crease gradually with each depression
as the vacuum is released from the
booster.
If the brakes do not operate properly, see
your NISSAN dealer.
