1998 CHEVROLET CAVALIER brakes

Downloaded from www.Manualslib.com manuals search engine Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light
on can lead
to an accident. If the light is still on after you’ve
pulled
off the road and stopped carefully, have
the vehicle towed for service.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake. The
light will stay on if your parking brake doesn’t release
fully. If it stays on after your parking brake is fully
released, it means you have
a brake problem.
Anti-Lock Brake System Warning Light
I With the anti-lock brake
system, this light will
come
on when you start your
engine and it will stay
on for three seconds.
That’s normal.
If the light stays
on, turn the ignition to OFF. Or, if the
light comes on when you’re driving, stop as
soon as
possible and
turn the ignition off. Then start the engine
again to reset the system. If the light still stays on, or
comes on again while you’re driving, your vehicle needs
service.
If the regular brake system warning light isn’t
on, you still have brakes, but you don’t have anti-lock
brakes. If the regular brake system warning light is also
on, you don’t have anti-lock brakes and there’s a
problem with your regular brakes. See “Brake System
Warning Light’’ earlier in this section.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to
RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn you if there is a problem.

take sudden action, as when a child darts into the street?
A person with even a moderate BAC might not be able
to react quickly enough to avoid the collision.
There’s something else about drinking and driving that
many people don’t know. Medical research shows that alcohol in a person’s system can make crash injuries
worse, especially injuries to the brain, spinal cord or
heart. This means that when anyone who has been
drinking
-- driver or passenger -- is in a crash, that
person’s chance of being killed or permanently disabled
is higher than
if the person had not been drinking.
Drinking and then driving is very dangerous. Your
reflexes, perceptions, attentiveness and judgment
can be affected by even a small amount of alcohol.
You can have a serious -- or even fatal -- collision
if you drive after drinking. Please don’t drink and
drive
or ride with a driver who has been drinking.
Ride home
in a cab; or if you’re with a group,
designate
a driver who will not drink.
Control of a Vehicle
You have three systems that make your vehicle go where
you want
it to go. They are the brakes, the steering and
the accelerator. All three systems have
to do their work
at the places where the tires meet the road.
Sometimes, as when you’re driving on snow
or ice, it’s
easy to ask more
of those control systems than the tires
and road can provide. That means you can lose control
of your vehicle.

Downloaded from www.Manualslib.com manuals search engine Braking
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That’s
perception time. Then you have to bring up your
foot and do it. That’s
reaction time.
Average reaction time is about 314 of a second. But
that’s only an average. It might be less with one driver
and as long as two or three seconds or more with
another. Age, physical condition, alertness, coordination
and eyesight all play a part. So do alcohol, drugs and
frustration. But even
in 3/4 of a second, a vehicle
moving at
60 mph (100 kmh) travels 66 feet (20 m).
That could be a lot of distance
in an emergency, so
keeping enough space between your vehicle and others
is important.
And, of course, actual stopping distances vary greatly
with the surface
of the road (whether it’s pavement or
gravel); the condition of the road (wet, dry, icy); tire
tread; the condition of your brakes; the weight of the
vehicle and the amount
of brake force applied. Avoid
needless heavy braking. Some people drive in
spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic. This is a
mistake. Your brakes may not have time to cool between
hard stops. Your brakes will wear out much faster
if you
do a lot of heavy braking. If you keep pace with the
traffic and allow realistic following distances, you will
eliminate a lot of unnecessary braking. That means
better braking and longer brake life.
If your engine ever stops while you’re driving, brake
normally but don’t pump your brakes. If you
do, the
pedal may get harder to push down. If your engine
stops, you will still have some power brake assist. But
you will use it when you brake. Once the power assist is
used up,
it may take longer to stop and the brake pedal
will be harder
to push.

Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent
a braking skid.
wnen
you start your engine, or when you begin to drive
away, your anti-lock brake system will check itself. You
may hear a momentary motor
or clicking noise while
this test is going on, and you may even notice that your
brake pedal moves or pulses a little. This is normal.
If there’s a problem with the
anti-lock brake system, this
warning light will stay on.
See “Anti-Lock Brake
System Warning Light” in
the Index.
Here’s how anti-lock works. Let’s say the road is wet.
You’re driving safely. Suddenly an animal jumps out in
front
of you.
You slam on the brakes. Here’s what happens with ABS.
A computer senses that wheels are slowing down. If one
of the wheels is about to stop rolling, the computer will
separately work the brakes at each front wheel and at
both rear wheels.

Downloaded from www.Manualslib.com manuals search engine The anti-lock system can change the brake pressure faster
than
any driver could. The computer is programmed to
make the
most of available tire and road conditions.
You can steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly. Remember:
Anti-lock doesn’t change the time
you need
to get your foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle in
front
of you, you won’t have time to apply your brakes
if that vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though you have
anti-lock brakes.
Using Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down
firmly and let anti-lock work
for you. You may feel a
slight brake pedal pulsation or notice some noise, but
this
is normal.
Enhanced Traction System
If your vehicle has the optional four-speed automatic
transaxle, it also has an Enhanced Traction System
(ETS) that limits wheel spin. This is especially useful
in slippery road conditions. The system operates only
when the transaxle shift lever
is in the REVERSE (R),
THIRD (3) or OVERDRIVE (@) position and the
system senses that one or both of the front wheels are
spinning or beginning to lose traction. When this
happens, the system reduces engine power and may
also upshift the transaxle
to limit wheel spin.

Downloaded from www.Manualslib.com manuals search engine Steering in Emergencies
There are times when steering can be more effective
than braking. For example, you come over a hill and find a truck stopped in your lane, or a car suddenly pulls
out from nowhere, or a child darts out from between
parked cars and stops right in front of you.
You can
avoid these problems by braking
-- if you can stop in
time. But sometimes
you can’t; there isn’t room.
That’s the time for evasive action
-- steering around
the problem.
Your vehicle can perform very well in emergencies
like these. First apply your brakes. (See “Braking in
Emergencies” earlier in this section.) It is better to
remove as much speed as you can from a possible
collision. Then steer around the problem, to the left or
right depending on the space available. An
emergency like this requires close attention and a
quick decision.
If you are holding the steering wheel at
the recommended
9 and 3 o’clock positions, you can
turn it a full 180 degrees very quickly without removing
either hand. But you have to act fast, steer quickly, and
just as quickly straighten the wheel once you have
avoided the object.
The fact that such emergency situations are always
possible is a good reason to practice defensive driving at
all times and wear safety belts properly.

Downloaded from www.Manualslib.com manuals search engine Loss of Control
Let’s review what driving experts say about what
happens when the three control systems (brakes, steering
and acceleration) don’t have enough friction where the
tires meet the road to do what the driver has asked.
In any emergency, don’t give up. Keep trying to
steer and constantly seek an escape route or area of
less danger.
Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not “overdriving”
those conditions. But skids
are always possible.
The three types of skids correspond to your vehicle’s
three control systems. In the braking skid, your wheels
aren’t rolling. In the steering or cornering skid, too
much speed or steering in a curve causes tires to slip and
lose cornering force. And in the acceleration skid, too
much throttle causes the driving wheels to spin,
A cornering skid is best handled by easing your foot off
the accelerator pedal.
If you have the Enhanced Traction System, remember:
It
helps avoid only the acceleration skid.
If you do not have the Enhanced Traction System, or if
the transaxle shift lever is not in the OVERDRIVE (0)
position, then an acceleration skid is also best handled
by easing your foot off the accelerator pedal.
If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want the
vehicle to go.
If you start steering quickly enough, your
vehicle may straighten out. Always be ready
for a
second skid if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel or other material is on the road. For safety, you’ll
want to slow down and adjust your driving to these
conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration or
braking (including engine braking by shifting to a lower
gear). Any sudden changes could cause the tires to
slide. You may not realize the surface is slippery until
your vehicle is skidding. Learn
to recognize warning
clues
-- such as enough water, ice or packed snow on
the road
to make a “mirrored surface” -- and slow down
when you have any doubt.
Remember: Any anti-lock brake system (ABS) helps
avoid only the braking
skid.

windshield wiper blades are in good shape, a heavy rain
can make it harder to
see road signs and traffic signals,
pavement markings, the edge of the road and even
people walking.
It’s wise to keep your windshield wiping equipment in
good shape and keep your windshield washer tank filled
with washer fluid. Replace your windshield wiper
inserts when they show signs
of streaking or missing
areas on the windshield, or when strips of rubber start to
separate from the inserts.
Driving too fast through large water puddles or even
going through some car washes can cause problems, too.
The water may affect your brakes. Try to avoid puddles.
But if you can’t, try to
slow down before you hit them.
