1994 CADILLAC SEVILLE brakes

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.
BRAKIN%
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
3/4 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 km/h) 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; and the condition
of your brakes.
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

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.
Anti-Lock Brakes (ABS)
Your Cadillac has an advanced electronic braking system that will help
prevent skidding.
This light on the
instrument panel will
go
on when you start
your vehicle.
ANTI-
LOCK (@!
When you start your vehicle and begin to drive away, you may hear a
momentary motor or clicking noise. And you may even notice that your
brake pedal moves a little while this is going on. This is the
ABS system
testing itself.
If there’s a problem with the anti-lock brake system, the
anti-lock brake system warning light will stay on.
See “Anti-lock Brake System Warning Light’’ in the Index.

Downloaded from www.Manualslib.com manuals search engine 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 the rear wheels.
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 speea ana
controls braking pressure accordingly.
Remember: Anti-lock doesn’t change the time you need to get your foot
up to the brake pedal.
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.
To Use Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down and let anti-lock
work for you. You may hear the anti-lock pump or motor operate, and
feel the brake pedal pulsate, but this is normal.
Traction Control System
Your vehicle has a traction control system that limits wheel spin. This is
especially useful in slippery road conditions. The system operates only if
it senses that one or both
of the front wheels are spinning or beginning to
lose traction. When this happens, the system works the front brakes and
reduces engine power (by shutting off fuel injectors) to limit wheel spin.
The “TRACTION ACTIVE” message will display on the Driver
Information Center when the traction control system is limiting wheel
spin. See “Driver Information Center Messages” in the Index. You may
feel the system working, or you may notice some noise, but this is normal.
If your vehicle is in cruise control when the traction control system begins
to limit wheel spin, the cruise control will automatically disengage. When
road conditions allow you to safely use it again, you may turn the cruise
control back on. (See “Cruise Control” in the Index.)
The “TRACTION DISABLED” message will display on the Driver
Information Center
if there’s a problem with your traction control system.
See “Driver Information Center Messages” in the Index. When this
message is displayed, the system will not limit wheel spin. Adjust your
driving accordingly.

Downloaded from www.Manualslib.com manuals search engine What should you do if this ever happens? Ease up on the accelerator
pedal, steer the vehicle the way you want it to go, and slow down.
Speed limit signs near curves warn that you should adjust your speed. Of
course, the posted speeds are based
on good weather and road
conditions. Under less favorable conditions you’ll want
to go slower.
If you need to reduce your speed as you approach a curve, do it before
you enter the curve, while your front wheels are straight ahead.
Try to adjust your speed so you can “drive” through the curve. Maintain a
reasonable, steady speed. Wait to accelerate until you are out of the
curve, and then accelerate gently into the straightaway.
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 Cadillac can perform
very well in emergencies like these. First apply
your brakes. 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.

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 Cadillac’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 and an acceleration skid are best handled by easing your
foot off the accelerator pedal.
If you have the traction control system, remember: It helps avoid only the
acceleration skid.
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

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.
Hydroplaning
Hydroplaning is dangerous. So much water can build up under your tires
that they can actually ride on the water. This can happen if the road
is wet
enough and you’re going fast enough. When your vehicle is hydroplaning,
it has little or no contact with the road.
Hydroplaning doesn’t happen often. But it can
