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.
Check parking brake adjustment. You may need to have
your brakes inspected more often if your driving habits
or conditions result in frequent braking.

Caliper/Knuckle 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.
