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 GM torque
specifications.
If you have rear drum brakes, they 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.
See Brake System Inspection on page 395.
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
Every time you make a moderate brake stop, your
disc 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.
If your brake pedal goes down farther than
normal, your rear drum brakes may need
adjustment. Adjust them by backing up and firmly
applying the brakes a few times.
