1997 Oldsmobile Aurora brakes

Brake Ad-iustment
NOTICE:
Continuing to drive with worn-out brake pads
could result
in costly brake repair.
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 retailer 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. 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.

Short TripKity Maintenance Schedule
The services shown in this schedule up to 100,000 miles
(166
000 krn) should be performed after 100,000 miles
(166
000 km) at the same intervals. The services shown
at 150,000 miles (240
000 km) should be performed at
the same interval after 150,000 miles (240
000 km).
See “Owner Checks and Services” and “Periodic
Maintenance Inspections” following.
Footnotes
-f The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to the
completion of the vehicle’s useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the maintenance
be recorded.
# Lubricate the suspension and steering linkage,
transaxle shift linkage, parking brake cable guides and
underbody contact points and linkage.
* Your vehicle has an Engine Oil Life Monitor. This
monitor will show
you when to change the oil -- usually
between
3,000 miles (5 000 km) and 7,500 miles
(12
500 km) since your last oil change. Under severe
conditions, the indicator may come on before
3,000 miles (5 000 km). Never drive your vehicle
more than
7,500 miles (12 500 krn) or 12 months,
(whichever occurs first), without an oil change.
The system won’t detect dust in the oil.
So if you
drive in a dusty area be sure to change your oil every
3,000 miles (5 000 km) or sooner if the CHANGE OIL
light comes on. Remember to reset the Oil Life Monitor
when the oil has been changed. For more information, see “Engine Oil Life Monitor” in the Index.
+ A good time to check your brakes is during tire
rotation. See “Brake System Inspection’’ under “Periodic
Maintenance Inspection” in Part
C of this schedule.

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.
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.
0 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.

Part C: Periodic Maintenance
Inspections
Listed below are inspections and services which should be
performed at least twice a year (for instance, each spring
and fall). You should let your
GM retailer’s service
department or other qualified service center do these jobs.
Make sure any necessary repairs are completed at once.
Proper procedures to perform these services may
be
found in a GM service manual. See “Service and Owner
Publications’’ in the Index.
Steering, Suspension and Front Drive Axle
Boot and Seal Inspection
Inspect the front and rear suspension and steering
system for damaged, loose or missing parts, signs of
wear or lack of lubrication. Inspect the power steering
lines and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc. Clean and then inspect the drive
axle boot seals for damage, tears or leakage. Replace
seals
if necessary.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body
near
the exhaust system. Look for broken, damaged,
missing or out-of-position parts as well as open seams, holes, loose connections or other conditions
which could
cause a heat build-up in the floor pan or could let
exhaust fumes into the vehicle. See “Engine Exhaust” in
the Index.
Radiator and Heater Hose Inspection
Inspect the hoses and have them replaced if they are
cracked, swollen or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed.
Throttle Linkage Inspection
Inspect the throttle linkage for interference or binding,
and for damage or missing parts. Replace parts as
needed. Replace any cables that have high effort or
excessive wear.
Do not lubricate accelerator and cruise
control cables.
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. You may need to
have your brakes inspected more often if your driving
habits or conditions result
in frequent braking.
