brakes BUICK REGAL 1997 Owner's Manual

When You Are Ready to Leave After
Parking
on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine;
0 Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling
a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine oil, belt, cooling system and brake adjustment.
Each
of these is covered in this manual, and the Index
will help you find them quickly. If you’re trailering, it’s
a good idea to review these sections before you start
your trip.
Check periodically to see that all hitch nuts and bolts
are tight.

When using concentrated washer fluid,
follow the manufacturer’s instructions for
adding water.
Don’t mix water with ready-to-use washer
fluid. Water can cause the solution to freeze
and damage your washer fluid tank and
other parts
of the washer system. Also,
water doesn’t clean as well as washer fluid.
Fill your washer fluid tank only
three-quarters full when
it’s very cold.
This
allows for expansion if freezing occurs,
which could damage the tank if it is
completely full.
Don’t use radiator antifreeze in your
windshield washer. It can damage your
washer system and paint.
Brakes
Brake Fluid
Your brake master cylinder reservoir is here. It is filled
with
DOT-3 brake fluid.
6-28
ProCarManuals.com

There are only two reasons why the brake fluid level in the
reservoir might go down. The
first is that the brake fluid
goes down
to an acceptable level during normal brake
lining wear. When new linings are put in, the fluid level
goes back up. The other reason is that fluid is leaking out
of the brake system.
If it is, you should have your brake
system fixed, since
a leak means that sooner or later your
brakes won’t work well, or won’t work at all.
So, it isn’t a good idea to “top off’ your brake fluid.
Adding brake fluid won’t correct a leak. If you add fluid
when your linings are worn, then you’ll have too much
fluid when you get new brake linings. You should add
(or remove) brake fluid, as necessary, only when work is
done on the brake hydraulic system.
If you have too much brake fluid, it can spill
on the engine. The fluid will burn
if the engine
is hot enough. You or others could be burned,
and your vehicle could be damaged. Add brake
fluid only when work is done on the brake
hydraulic system.
When your brake fluid falls to a low level, your brake
warning light will come on. See “Brake System Warning
Light” in the Index.
What to Add
When you do need brake fluid, use only DOT-3
brake fluid -- such as Delco Supreme 11 @ (GM Part
No. 12377967). Use new brake fluid from a sealed
container only.
Always clean the brake fluid reservoir cap and the area
around the cap before removing it. This will help keep
dirt from entering the reservoir.
1 CAUTIC
With the wrong kind of fluid in your brake
system, your brakes may not work well, or they
may not even work at all. This could cause a
crash. Always use the proper brake fluid.
ProCarManuals.com

NOTICE:

Using the wrong fluid can badly damage
brake system parts. For example, just a few
drops
of mineral-based oil, such as engine
oil, in your brake system can damage brake
system parts
so badly that they’ll have to be
replaced. Don’t let someone put in the
wrong kind
of fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged. Be careful not
to spill brake fluid
on your vehicle. If you do, wash it off
immediately. See “Appearance Care” in
the Index.
Brake Wear
Your Buick has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that
make a high-pitched warning sound when the brake
pads are worn and new pads are needed. The
sound
may come and go or be heard all the time your vehicle
is moving (except when you are pushing on the brake
pedal firmly).
The brake wear warning sound means that soon
your brakes won’t work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
I NOTICE:
~~
Continuing to drive with worn-out brake pads
could result in costly brake repair.
6-30
ProCarManuals.com

Some driving conditions or climates may cause a
brake squeal when the brakes are first applied or lightly
applied. This does
not mean something is wrong with
your brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly torque wheel nuts
in
the proper sequence to GM specifications.
Brake linings should always be replaced as complete
axle sets.
See “Brake System Inspection” in Section
7 of this
manual under Part
C “Periodic Maintenance
Inspections.”
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase
in pedal
travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.
Replacing Brake System Parts
The braking system on a modern vehicle is complex.
Its many parts have to be of top quality and work well
together if the vehicle is to have really good braking.
Your vehicle was designed and tested with top-quality
GM brake parts. When you replace parts
of your braking
system
-- for example, when your brake linings wear
down and you have to have new ones put in
-- be sure
you get new approved GM replacement parts. If you
don’t, your brakes may no longer work properly. For
example,
if someone puts in brake linings that are wrong
for your vehicle, the balance between your front and
rear brakes can change
-- for the worse. The braking
performance you’ve come
to expect can change in many
other ways if someone puts in the wrong replacement
brake parts.
Battery
Every new Buick has a Delco Freedom@ battery. You
never have to add water to one of these. When it’s time
for a new battery, we recommend a Delco Freedom
battery. Get one that has the replacement number shown
on the original battery’s label.

conditions,
the indicator may come on before

Ignition Transaxle Lock Check
While parked, and with the parking brake
set, try to turn
the ignition key to LOCK in each shift lever position.
0 The key should turn to LOCK only when the shift
lever is in PARK
(P).
0 The key should come out only in LOCK.
Parking Brake and Automatic Transaxle PARK
(P)
Mechanism Check
When you are doing this check, your vehicle
could begin to move. You or others could be
injured and property could be damaged. Make
sure there is room in front
of your vehicle in case
it begins to roll. Be ready to apply the regular
brake at once should the vehicle begin to move. Park on
a fairly steep hill, with the vehicle facing
downhill. Keeping your foot on the regular brake, set the
parking brake.

To check the parking brake’s holding ability: With
the engine running and transaxle in NEUTRAL
(N),
slowly remove foot pressure from the regular brake
pedal.
Do this until the vehicle is held by the parking
brake only.
To check the PARK (P) mechanism’s holding ability:
With the engine running, shift to PARK (P). Then
release all brakes.
Underbody Flushing Service
At least every spring, use plain water
to flush any
corrosive materials from
the underbody. Take care to
clean thoroughly any areas where mud and other debris
can collect.
