1993 BUICK REGAL brake fluid

Safety Chains
You should always attach chains between your vehicle
and your trailer. Cross the safety chains under the
tongue of the trailer
so that the tongue will not drop to
the road if it becomes separated from the hitch.
Instructions about safety chains may be provided by the
hitch manufacturer or by the trailer manufacturer.
Follow the manufacturer’s recommendation for
attaching safety chains. Always leave just enough slack
so you can turn with your rig. And, never allow safety
chains to drag on the ground.
Trailer Brakes
If your trailer weighs more than 1,000 pounds (450 kg)
loaded, then it needs
its own brakes -- and they must be
adequate. Be sure
to read and follow the instructions for
the trailer brakes
so you’ll be able to install, adjust and
maintain them properly. If your vehicle has anti-lock
brakes, do not try
to tap into your vehicle’s brake
system. If you do, both brake systems won’t work well,
or at all. Even if your vehicle doesn’t have anti-lock
brakes, don’t tap into your vehicle’s brake system if
the
trailer’s brake system will use more than 0.02 cubic inch
(0.3 cc) of fluid from your vehicle’s master cylinder. If it
does, both braking systems won’t work well.
You could
even
lose your brakes.
Will the trailer brake parts take 3,000 psi (20 650
kPa) of pressure? If not, the trailer brake system
must not be used with your vehicle.
If everything checks out this far, then make the brake
fluid tap at the upper rear master cylinder port. But
don’t
use copper tubing for this. If you do, it will
bend and finally break
off. Use steel brake tubing.
Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for
the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the
trailer. And always keep
in mind that the vehicle you are
driving is
now a good deal longer and not nearly so
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform,
safety chains, electrical connector, lights, tires and
mirror adjustment. If the trailer has electric brakes, start
your vehicle and trailer moving and then apply the
trailer brake controller by hand to be sure
the brakes are
working. This lets you check your electrical connection
at the same time.
During your trip, check occasionally
to be sure that the
load is secure, and that the lights and any trailer brakes
are still working.

Parking on Hills
You really should not park your vehicle, with a trailer
attached, on a hill. If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if
you ever have to park your rig on a hill, here’s
how to do it:
1.
2.
3.
4.
5.
Apply your regular brakes, but don’t shift into “P’
(Park) yet.
Have someone place chocks under the trailer wheels.
When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
Reapply the regular brakes. Then apply your parking
brake, and then shift to “P” (Park).
Release the regular brakes.
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;
Shift into a gear; and
0 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.

Automatic Transaxle Fluid
When to Check and Change:
A good time to check your automatic transaxle fluid
level is when
the engine oil is changed. Refer to the
Maintenance Schedule to determine when to change
your fluid. See “Scheduled Maintenance Services” in
the Index.
How to Check:
Because this operation can be a little difficult, you may
choose to have this done at a Buick dealership Service
Department.
If you do it yourself, be sure to follow all the
instructions here, or you could get a false reading on the
dipstick.
NOTICE:
Too much or too little fluid can damage your
transaxle.
Too much can mean that some of the
fluid could come out and fall
on hot engine parts,
starting a fire. Be sure to get an accurate reading
if you check your transaxle fluid.
Wait at least 30 minutes before checking the transaxle
fluid level if you have been driving:
When outside temperatures are above 90°F (32 ” C).
At high speed for quite a while.
0 In heavy traffic -- especially in hot weather.
0 While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is
180 F to 200 F (82 C
Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above
50°F
(10°C). If it’s colder than 50°F (lO°C), you may have
to drive longer.
To check the fluid level:
Park your vehicle on a level place.

Brake Master Cylinder
Your brake master cylinder is here. It is filled with
DOT-3 brake fluid.
There are only two reasons why the brake fluid level in
your master cylinder might @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.

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
-stem.
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
N0.1052535). Use new brake fluid from a sealed
container only.

DOT-5 silicone brake fluid can damage
your vehicle. Don’t use it.
Don’t let someone put
in the wrong kind of
fluid. 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.
Brake fluid can damage paint,
so be careful
not to spill brake fluid on your vehicle.
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.
Vehicles we design and test have top-quality GM brake
parts in them, as your Buick does when
it is new. 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 genuine
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

Explanation of Scheduled Maintenance
Services
Below are explanations of the services listed in Schedule
I and Schedule 11.
The proper fluids and lubricants to use are listed in
Section D. Make sure whoever services your vehicle uses
these. All parts should be replaced and all necessary
repairs done before
you or anyone else drives the vehicle.
NOTE: To determine your engine’s displacement and
code, see “Engine Identification” in the Index.
1. Engine Oil and Filter Change* -- Always use SG
Energy Conserving I1 oils of proper viscosity. The
“SG” designation may be shown alone or in
combination with others, such as “SG/CC”, ,“SG/CD”
or
“SF, SG, CC,” etc. To determine the preferred
viscosity for your vehicle’s engine (e.g., SAE 5W-30
or SAE 10W-30), see “Engine Oil”
in the Index.
2. Chassis Lubrication -- Lubricate the transaxle shift
linkage, parking brake cable guides, underbody
contact points and linkage. If your vehicle is
equipped with grease fittings, lubricate
the
suspension and steering linkage. 3.
Throttle Body Mounting
Bolt Torque* -- Check
the torque
of the mounting bolts and/or nuts.
4. Tire and Wheel Rotation and Inspection -- For
proper wear and maximum tire life, rotate your tires
following the instructions
in this manual. See “Tires,
Inspection
& Rotation” in the Index. Check the tires
for uneven wear or damage. If you see irregular or
premature wear, check the wheel alignment. Check
for damaged wheels also.
5. Engine Accessory Drive Belt(s) Inspection --
Inspect the belt(s) for cracks, fraying, wear and
proper tension. Replace as needed.
6. Cooling System Service* -- Drain, flush and refill
the system
with new or approved recycled coolant
conforming to GM Specification 1825M. Keep
coolant at the proper mixture as specified. See
“Coolant”
in the Index. This provides proper freeze
protection, corrosion inhibitor level and engine
operating temperature.
Inspect hoses and replace
if they are cracked,
swollen or deteriorated. Tighten screw-type hose
clamps. Clean the outside
of the radiator and air
* An Emission Control Service.
The
U.S. Environmental Protection Agency has determined that the failure to perform this maintenance item will not nullify the emission warranty or limit recall liability prior tothe completion of vehicle useful life. General Motors, however, urges that all recommended maintenance \
services he performed at the indicatcd intervals and the maintenance be recorded in ”Section E:Maintenance Record”.
