brake fluid CHEVROLET S10 1993 2.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine Remember: The rear wheel antilock braking system (RWAL) helps \
avoid only
a rear braking skid. In a braking skid (where the front wheels \
are no longer
rolling), release enough pressure on the brakes to get the front wheels rolling
again. This restores steering control. Push the brake pedal dow\
n steadily
when you have to stop suddenly. As long as the front wheels \
are rolling, you
will have steering control. Steer the way you want to go.
Off-Road Driving with Your FoutNVheel
Drive Vehick
This off-road guide is for vehicles that have four-wheel drive.\
Also, see
“Antilock Brakes’’ in the Index.
If your vehicle doesn’t have four-wheel drive,
you shouldn’t drive off-road unless you’re on a level, so\
lid surface.
Off-road driving can be great fun. But it does have some definite hazards.
The greatest of these is the terrain itself.
“Off-roading” means you’ve left the great North American\
road system behind.
Traffic lanes aren’t marked. Curves aren’t banked. There a\
re no road signs.
Surfaces can be slippery, rough, uphill or downhill. In short, \
you’ve gone right
back to nature.
Off-road driving involves some new skills. And that’s why it’s very important
that you read this guide. You’ll find many driving tips and suggestio\
ns. These
will help make your off-road driving safer and more enjoyable. \
Before You Go Off-Roading
There are some things to do before you go outi For example, be sure to
have all necessary maintenance and service work done. Be sure \
you read all
the information about your four-wheel drive vehicle in this man\
ual.
Is there
enough fuel?
Is the spare tire fully inflated? Are the fluid levels up where
they should be? What are the local laws that apply to off-roading where you’ll
be driving?
If you don’t know, you should check with law enforcement people\

in the area. Will you be on someone’s private land?
If so, be sure to get the
necessary permission.
Loading Your Vehicle for Off-Road Driving
There are some important things to remember about how to load your

Your Driving and the Road
Hill and Mountain Roads
I
AM470001
Driving on steep hills or mountains is different from driving in flat or rolling
terrain.
If you drive regularly in steep country, or if you're planning to visit
there, here are some tips that can make your trips safer and \
more enjoyable.
(See "Off-Road Driving" in the Index for information about driving off-road.)
Keep your vehicle in good shape. Check all fluid levels and also the
brakes, tires, cooling system and transmission. These parts can \
work
hard on mountain roads.
Know how to go down hills. The most important thing to know is this: let
your engine do some of the slowing down. Don't make your brak\
es do
it
all. Shift to a lower gear when you go down a steep or long hill. That
way, you will
slow down without excessive use of your brakes.
If you don't shift down, your brakes could get
so hot that they
wouldn't work well. You would then have poor braking or even none
going down a hill. You could crash. Shift down to let your engine
1 assist your brakes on a steep downhill slope.

Downloaded from www.Manualslib.com manuals search engine Safety Chains
You should always attach chains between your vehicle and your trail\
er. 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 atta\
ching 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 to install, adjust and maintain them properly.
And:
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~~) 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 vehi\
cle.
If everything checks out this far, then make the brake fluid tap \
at the
port on the master cylinder that sends fluid to the rear brak\
es. 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 setti\
ng out
for the open road, you’ll want to get to know your rig. A\
cquaint 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 trail\
er brake controller
by hand to be sure the brakes are working. This lets you che\
ck 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.

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 esp\
ecially important in trailer operation are automatic transmission fluid (don’t ove\
rfill),
engine oil, axle lubricant, belt, cooling system, and brake adj\
ustment. 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.
Trailer Light Wiring
See “Trailer Wiring Harness” in the Index.
Power Winches
If you wish to use a power winch on your vehicle, only use it when your
vehicle is stationary or anchored.
NOTICE
Use the regular brakes, set the parking brake Or UIWK ihe wheels IW keep
your vehicle from rolling.

sure the vehicles aren’t touching each other. If they are, \
it could cause
a
ground connection you don’t want. You wouldn’t be able to start your
vehicle, and the bad grounding could damage the electrical syst\
ems.
1 CAUTION
* You could be injured if the vehicles roll. Set the parking brake \
firmly I
on each vehicle. Put an automatic transmission in P (Park) or a
manual transmission in
N (Neutral).
If you have a four-wheel-drive vehicle with a manual transfer case\

shift lever, be sure the tra-fer case is not in
N (Neut--’).
3. Turn off the ignition on both vehicles. Turn off all lights that aren’t
I
needed, and radios. This will avoid sparks and help save both \
batteries.
And it could save your radio!
4. Open the hoods and locate the batteries. Find the positive (t) arlu
negative
(-) terminals on each battery.
* Using a match near a battery can cause battery gas to explode. I
People have been hurt doing this, and some have been blinded. \
Use
a flashlight if you need more light.
You don’t need to add water to the Delco Freedom@ battery \
installer’
in every new
GM vehicle. But if a battery has filler caps, be sure thG
right amount of fluid is there.
If it is low, add water to take care of
that first.
If you don’t, explosive gas could be present.
Battery fluid contains acid that can burn you. Don’t get it on you.
If
you accidentally get it in your eyes or on your skin, flush the place
I with water and get medical help immediately.
5. Check that the jumper cables don’t have loose or missing insulation. If
they do, you could get a shock. The vehicles could be damaged, too.

Hood Release
To open the hood, first pull the handle inside the vehicle on th\
e lower left
side of the instrument panel. Then
go to the front of the vehicle and release
the secondary hood release. Lift the hood, release the hood pr\
op from its
retainer and put the hood prop into the slot in the hood. You may have a
light that comes on when you lift the hood.
L
Thing's that burn can .get on hot engine parts and s'hrt a fire. These I
include liqwids like gasoline, oil, coolant, brake fluid, windshiield
washer and .other fluids, and plastic oir rubber. You or others could
be blurned. Be careful not
to drop or spill thing.s that will bum onto a
hot eng,ine.
L
Before closing the hood, be sure all the filler caps are on properly. Then lift
the hood to relieve pressure on the hood prop.
Remove the hood prop from the slot in the hood and return th\
e prop to its
retainer. Then just pull the hood down and close
it firmly.

Downloaded from www.Manualslib.com manuals search engine To check the fluid hot or cold:
Park your vehicle on a level place.
Place the shift lever in P (Park) with the parking brake applied.
With your foot on the brake pedal, move the shift lever through each
gear range, pausing for about three seconds in each range. Then,
position the shift lever in
P (Park).
Let the engine run at idle for three minutes or more.
Then, without shutting
off the engine, follow these steps:

Your brake master cylinder is here. It is filled with DOT-3 brake fluid.

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. I
Refer to the Maintenance Schedule to determine when to check your brake
fluid. See “Periodic Maintenance Inspections” in the Index.

Service & Appearance Care
To Check Brake Fluid:
You can check the brake fluid without taking off the cap. Just look at the
windows on the brake fluid reservoir. The fluid levels should be above
MIN. If
they aren’t, have your brake system checked to see if there is a leak.
After work is done on the brake hydraulic system, make sure t\
he levels are above
MIN and below the top of each window.
What To Add
When you do need brake fluid, use only DOT-3 brake fluid-such as Delco
Supreme
11 @ (GM Part No. 1052535). Use new brake fluid from a sealed
container only.
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 vehicle 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
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.
Fluid Leak Check
After the vehicle has been parked for a while, inspect the su\
rface under the
vehicle for water, oil, fuel or other fluids. Water dripping from the air
conditioning system after
it has been used is normal. If you notice fuel leaks
or fumes, the causes should be found and corrected at once.
