brake CHEVROLET TRACKER 1993 Service Manual

Know how to go uphill. You may
want to shift down to a lower gear.
The lower gears help cool your
engine and transmission, and you can
climb
the hill better.
Stay in your own lane when driving
on two-lane roads in hills or
mountains. Don’t swing
wide or cut
across
the center of the road. Drive at
speeds that let you stay in your own
lane. That way, you won’t be
surprised by a vehicle coming toward
you in the same lane.
It takes longer to pass another vehicle
when you’re going uphill. You’ll want
to leave extra room to pass.
If a
vehicle
is passing you and doesn’t have enough
room, slow down to
make it easier for the other vehicle to
get by.
As you go over the top of a hill, be
alert. There could be something in
your lane, like a stalled car or an
accident.
You may see highway signs on
mountains that warn of special
problems. Examples are long grades,
passing or no-passing zones, a falling
rocks area, or winding roads. Be alert
to these and take appropriate action.

Hills and mountains mean spectacular
scenery. But please be careful where
you stop if you decide to look at the
view or take pictures.
Look. for pull-offs
or parking areas provided for scenic
viewing.
Another part of this manual tells how to
use your parking brake (see “Parking
Brake” in
the Index). But on a mountain
or steep hill, you can do one more
thing. You can turn your front wheels to
keep your vehicle from rolling downhill
or out into traffic.
Here’s how:

Torque Lock (Automatic
Transmission)
If you are parking on a hill and you
don’t shift your transmission into
P
(Park) properly, the weight of the
vehicle may put too much force on the
parking pawl in the transmission.
You
may find it difficult to pull the shift
lever out of
P (Park). This is called “torque
lock.”
To prevent torque lock,
always be sure to shift into
P (Park)
properly before you leave the driver’s
seat.
To find out how, see ‘‘Shifting into
P (Park)” in the Index.
When you are ready to drive, move the
shift lever out
of P (Park) BEFORE you
release the parking brake.
If torque lock does occur, you may need
to have another vehicle push yours a
little uphill
to take some of the pressure
from the transmission,
so you can pull
the shift lever out
of P (Park).
Winter Driving
Here are some tips for winter driving:
Have your Geo in good shape for
winter. Be sure your engine coolant
mix is correct.
Snow tires can help in loose snow,
but they may give you less traction on
ice than regular tires.
If you do not
expect
to be driving in deep snow, but
may have to travel over ice, you may
not want
to switch to snow tires at all.

Your anti-lock brakes improve your
ability to make a hard stop on a slippery
road. Even though you have the
anti-lock braking system, you’ll want to
begin stopping sooner than you would
on dry pavement. See “Anti-lock” in
the Index.
Allow greater following distance on any
slippery road.
Watch for slippery spots. The road
might be fine until
you hit a spot
that’s covered with ice. On an
otherwise clear road, ice patches may
appear
in shaded areas where the sun
can’t reach: around clumps of trees,
behind buildings, or under bridges. Sometimes the
surface
of a curve or
an overpass may remain icy
when the
surrounding roads are clear. If you
see a patch
of ice ahead of you, brake
before you are on it. Try not to brake
while you’re actually on the ice, and
avoid sudden steering maneuvers.
If You’re Caught in a Blizzard
If you are stopped by heavy snow, you
could be
in a serious situation. You
should probably stay with your vehicle
unless you know for sure that you are
near help and you can hike through the
snow. Here are some things to do to
summon help and keep yourself and
your passengers safe: Turn on your
hazard flashers. Tie a red cloth to your
vehicle to alert police that you’ve been
stopped by the snow. Put on extra
clothing or wrap a blanket around you.

(CO) from your exhaust can get into
your vehicle (see “Carbon
Monoxide’’
in the Index). Dirt and
water can, too.
The bumpers on your vehicle are not
intended for hitches.
Do not attach
rental hitches or other bumper-type
hitches to them. Use only a
frame-mounted hitch that does
not
attach to the bumper.
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.
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.
ProCarManuals.com

Your Driving and the Road
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 port
on the master cylinder that sends fluid
to the rear brakes. 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.

Your Driving and the Road
they are not. It’s important to check
occasionally to be sure the trailer bulbs
are still working.
Driving on Grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift down, you
might have to use your brakes
so much
that they would get hot and no longer
work well.
On a long uphill grade, shift down and
reduce your speed
to around 45 mph
(70 km/h) to reduce the possibility of
engine and transmission overheating.
If your trailer weighs more than 1,000
pounds
(450 kg), and you have a manual
transmission with fifth gear, it’s better
not to use fifth gear. Just drive
in fourth
gear (or, as you need to, a lower gear).
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. Apply your regular brakes, but don’t shift into

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
transmission fluid (don’t overfill),
engine oil, axle lubricant, belts, 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.
