brake BUICK REGAL 1998 Repair Manual

I Maintenance Schedule I
The services shown in this schedule up to 100,000 miles
(166
000 km) 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
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.
* Your vehicle has an Engine Oil Life Monitor. This
monitor will show you when to change the engine oil
and filter
-- 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 km) or 12 months
without an oil and filter change.
The system won’t detect dust in the oil.
So if you drive
in a dusty area, be sure to change your oil and filter
every
3,000 miles (5 000 km) or sooner if the CHANGE
OIL SOON light comes
on. Remember to reset the Oil
Life Monitor when the oil has been changed. For more
information,
see “Change Oil Soon Light” in the Index.
+ A good time to check your brakes is during tire
rotation. See “Brake System Inspection” under “Periodic
Maintenance Inspections” in Part C of this schedule.

1 A C A UTION:
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.
To check the parking brake’s holding ability: With
the engine running and transaxle in NEUTRAL

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 dealer’s service department
or other qualij?ed 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 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.
Engine Cooling System Inspection
Inspect the hoses and have them replaced if they are
cracked, swollen or deteriorated. Inspect
all pipes, fittings
and clamps; replace as needed. Clean the outside of the
radiator and air conditioning condenser.
To help ensure
proper operation, a pressure test
of the cooling system and
pressure cap is recommended at least once a year.
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.
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.
