the brake pads are worn and new pads are needed. The sound m\
ay come and go or be heard all the time your vehicle is moving (except when you are
pushing on the brake pedal firmly).

4 brakes won’t work well. That could lead to an accident. When you
hear the brake wear warning sound, have your vehicle serviced. \

brakes are first applied or lightly applied. This does not mean something is
wrong with your brakes.

rear brake rubbing noise, have the rear brake linings inspected\
. Also, the rear
brake drums should be removed and inspected each time the tires are
removed for rotation or changing. When

and maximum tire life, rotate tires at the first
6,000 miles (1 0 000
kilometers) for Schedule I or 7,500 miles (12 500 kilometers) for
Schedule
II and then every 7,500 miles (12 500 kilometers) thereafter.
Follow the instructions and patterns shown in Section

uneven wear or damage.
If irregular or premature wear is apparent,
check wheel alignment.
Also, check for damaged wheels. See “Tires” in
the Index for more information.

BRAKE SYSTEM INSPECTION -When the engine oil is changed,
inspect the lines and hoses for proper hookup, binding, leaks, \
cracks,
chafing, etc. Check the parking brake adjustment, and the fluid\
level in
the master cylinder.
A low fluid level can indicate worn disc brake pads
which may need
to be serviced$
When the wheels are removed for rotation, inspect disc brake p\
ads for
wear and rotors for surface condition.
Also inspect drum brake linings for
wear and cracks. Inspect other brake parts, including drums, wh\
eel
cylinders, parking brake, etc., at the same time.
Inspect brakes more often if driving habits or conditions result in
frequent braking.
tA fluid loss in these systems may indicate a problem. Have them inspected
and repaired at once.
