Brake Adjustment; Replacing Brake System Parts; Brake Pedal Travel - GMC 1999 Envoy Owner's Manual

Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
your brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly torque wheel nuts in the
proper sequence to GM specifications.
Brake linings should always be replaced as complete
axle sets.
See "Brake System Inspection" in Section 7
of this manual under Part C "Periodic
Maintenance Inspections."

Brake Pedal Travel

See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel. This could be a sign of brake trouble.

Brake Adjustment

for your vehicle, the balance between your front and

performance you've come to expect can change in many
other ways if someone puts in the wrong replacement
brake parts.
