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.
CaliperKnuckle 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 dealer's service department
or qualified service center for additional information.
