brake PONTIAC FIREBIRD 1998 Repair Manual

Used Replacement Wheels
Using the wrong replacement wheels, wheel
bolts or wheel nuts on your vehicle can be
dangerous.
It could affect the braking and
handling
of your vehicle, make your tires lose
air and make you lose control. You could have
a collision in which you or others could be
injured.
Always use the correct wheel, wheel
bolts and wheel nuts for replacement.
I NOTICE:
~
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire or
tire chain clearance to the body and chassis.
See “Changing a Flat Tire” in the Index for
more information.
Putting a used wheel on your vehicle is
dangerous. You can’t know how it’s been used or
how far it’s been driven. It could fail suddenly
and cause an accident.
If you have to replace a
wheel, use
a new GM original equipment wheel.
Tire Chains
I NOTICE:
If your vehicle has P235/55R16, P245/50ZR16 or
P275/40ZR17 size tires, don’t use tire chains.
They can damage your vehicle because there’s
not enough clearance.

The other two are in the engine compartment. Open the
cover on either
of the boxes to expose the fuses.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace
the fuse. Be sure you
replace a bad fuse with a new one of the correct size.
If you ever have a problem on the road and don't have a
spare fuse, you can borrow one. Just pick some feature
of your car that you
can get along without -- like the
radio or cigarette lighter
-- and use its fuse, if it is the
size
you need. Replace it as soon as you can.

Starter Switch Check
r
Brake-Transmission Shift Interlock (BTSI) Check
(Automatic Transmission)
When you are doing this check, the vehicle could
move suddenly.
If it does, you or others could be
injured. Follow the steps below.
1. Before you start, be sure you have enough room around the vehicle.
2. Firmly apply both the parking brake (see “Parking
Brake,’
in the Index if necessary) and the regular brake.
NOTE: Do not use the accelerator pedal, and be
ready to turn
off the engine immediately if it starts.
3. On automatic transmission vehicles, try to start the
engine
in each gear. The starter should work only in
PARK (P) or NEUTRAL
(N). If the starter works in
any other position, your vehicle needs service.
On manual transmission vehicles, put the shift lever
in
NEUTRAL (N), push the clutch down halfway
and
try to start the engine. The starter should work
only when the clutch
is pushed down all the way to
the
floor. If the starter works when the clutch isn’t
pushed all the way down,
your vehicle needs service.
-
A CAUTION:
When you are doing this check, the vehicle could
move suddenly.
If it does, you or others could be
injured. Follow the steps below.
1
1. Before you start, be sure you have enough room
around the vehicle.
It should be parked on a
level surface.
2. Firmly apply the parking brake (see “Parking Brake”
in the Index if necessary).
NOTE: Be ready to apply the regular brake
immediately if
the vehicle begins to move.
3. With the engine off, turn the key to the RUN
position, but don’t start the engine. Without applying
the regular brake,
try to move the shift lever out of
PARK
(P) with normal effort. If the shift lever
moves out of PARK
(P), your vehicle’s BTSI
needs service.

Ignition Transmission Lock Check
While parked, and with the
parking brake set, try to turn
the ignition key to LOCK in each shift lever position.
With an automatic transmission, the key should turn
to LOCK only when the shift lever is in PARK (P).
With a manual transmission, the key should turn to
On vehicles with a key release button, try to turn the key
to LOCK without pressing the button. The key should
turn to LOCK only when you press the key button. LOCK only when the
shift lever is in REVERSE (R).
On
all vehicles, the key should come out only in LOCK.
Parking Brake and Automatic Transmission
PA-” :P) M ’nanisl k
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 transmission in
NEUTRAL (N), slowly remove foot pressure from
the regular brake pedal. Do this until the vehicle is
held by the parking brake only.
0 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.
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.

Throttle System Inspection
Inspect the throttle system for interference or binding,
and for damaged or missing parts. Replace parts as
needed. Replace any components that have high effort
or excessive wear.
Do not lubricate accelerator and
cruise control cables.
Rear Axle Service
Check the gear lubricant level in the rear axle and add if
needed. See “Rear Axle” in the Index. A fluid loss
may indicate
a problem. Check the axle and repair it
if needed.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear and rotors
for surface condition. Inspect other brake parts, including calipers, parking brake, etc. Check parking
brake adjustment. You may need to have your brakes
inspected more often if your driving habits or conditions
result in frequent braking.
