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 front caliper
inspection procedure.
As
necessary, front 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.
