Vehicle Care 10-25

Some driving conditions or climates

can cause a brake squeal when the

brakes are first applied or lightly

applied. This does not mean

something is wrong with the 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 torque

specifications in Capacities and

Specifications on page 12‑2.

If the vehicle has rear drum brakes,

they do not have wear indicators,

but if a rear brake rubbing noise is

heard, have the rear brake linings

inspected immediately. Rear brake

drums should be removed and

inspected each time the tires are

removed for rotation or changing.

Drum brakes have an inspection

hole to inspect lining wear during

scheduled maintenance. When the

front brake pads are replaced, have

the rear brakes inspected, too.

Brake linings should always be

replaced as complete axle sets.

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

that brake service might be

required.

Brake Adjustment

Every moderate brake stop, the disc

brakes adjust for wear. If rarely

making moderate or heavier brake

stops, the brakes might not adjust

correctly. Very carefully making a

few moderate brake stops about

every 1 600 km (1,000 miles) will

adjust the brakes properly.

If the vehicle has rear drum brakes

and the brake pedal goes down

farther than normal, the rear drum

brakes might need adjustment.

Adjust them by backing up and

firmly applying the brakes a few

times.

Replacing Brake System Parts

The braking system on a vehicle is

complex. Its many parts have to be

of top quality and work well together

if the vehicle is to have really good

braking. The vehicle was designed

and tested with top-quality brake

parts. When parts of the braking

system are replaced, be sure to get

new, approved replacement parts.

If this is not done, the brakes might

not work properly. For example,

installing disc brake pads that are

wrong for the vehicle, can change

the balance between the front and

rear brakes — for the worse. The

braking performance expected can

change in many other ways if the

wrong replacement brake parts are

installed.
