Saturn 2004 Ion - Manual (Page 270)

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).
{ CAUTION:
The brake wear warning sound means that
soon your brakes will not 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 tighten wheel nuts in
the proper sequence to Saturn specifications.
The rear drum brakes do not have wear indicators,
but if you ever hear a rear brake rubbing noise, have the
rear brake linings inspected immediately. Also, the
rear brake drums should be removed and inspected
each time 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.
Brake Pedal Travel
See your retailer 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
Every time you make a moderate brake stop, your brakes
adjust for wear. If you rarely make a moderate or heavier
stop, then your brakes might not adjust correctly. If you
drive in that way, then — very carefully — make a few
moderate brake stops about every 1,000 miles
(1 600 km), so your brakes will adjust properly.
