Brake Wear
Your vehicle has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that
make a high-pitched warning sound when the brake
pads are worn and new pads are needed. The sound
may come and go or be heard all the time your vehicle
is moving (except when you are pushing on the brake
pedal firmly).
The brake wear warning sound means that soon
your brakes won't work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
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.
Your rear drum brakes don't have wear indicators,
but if you ever hear a rear brake rubbing noise, have t
rear brake linings inspected immediately. Also, the rear
brake drums should be removed and inspected each tim
the tires are removed for rotation or changing. When
you have the front brake pads replaced, have the rear
brakes inspected, too.
Brake linings should always be replaced as complete
axle sets.
See "Brake System Inspection" in Section 7 of this
manual under P a r t 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.
