11. Tighten the wheel nuts
firmly in a criss-cross
sequence, as shown.
NOTICE:
Improperly tightened wheel nuts can lead to
brake pulsation and rotor damage.
To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque specification.
Incorrect wheel nuts
or improperly tightened
wheel nuts can cause the wheel to become loose
and even come
off. This could lead to an accident.
Be sure to use the correct wheel nuts. If you have
to replace them, be sure to get new
GM original
equipment wheel nuts.
Stop somewhere as soon as you can and have the
nuts tightened with
a torque wrench to 100 lb-ft
(140 N-m). Don’t
try to put
a wheel cover on your compact spare
tire. It won’t fit. Store the wheel cover and wheel nut
caps in the
trunk until you have the flat tire repaired
or replaced.

I NOTICE:
Wheel covers won’t fit on your compact spare.

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. Also inspect drum brake linings
for wear and cracks. Inspect other brake parts, including
drums, wheel cylinders, calipers, parking brake, etc. The
parking brake is self-adjusting
and no manual
adjustment is required. You
may need to have your
brakes inspected more often if your driving habits or
conditions result in frequent braking.
CalipedKnuckle Maintenance Inspection
If you operate your vehicle in a highly corrosive
environment, as indicated
by the shaded areas on the
map following this text, your vehicle may require
additional brake service. Refer to the appropriate
GM
Service Bulletin for the proper caliper inspection
procedure.
As necessary, caliper pins and knuckle brake pad
abutments should be lubricated at every other tire
rotation. Also, see your
GM retailer’s service
department or qualified service center for
additional information.
