however, they may be heard at any time while braking and can be
aggravated by environmental conditions such as cold, heat, moisture,
road dust, salt or mud. If a “metal-to-metal,” “continuous grinding” or
“continuous squeal” sound is present while braking, the brake linings
may be worn-out and should be inspected by an authorized dealer.
Refer to Brake system warning
light in the Warning lights and
chimes section of the Instrument
Cluster chapter for information.
WARNING: If you are driving down a long or steep hill, shift to
a lower gear. Do not apply your brakes continuously, as they may
overheat and become less effective.
Under normal operating conditions, brake dust may accumulate on the
wheels. Some brake dust is inevitable as brakes wear and does not
contribute to brake noise. The use of modern friction materials with
emphasis on improved performance and environmental considerations
can lead to more dust than in the past. Brake dust can be cleaned by
weekly washing with soapy water and a soft sponge. Heavier deposits can
be removed with Motorcraft
௡ Wheel and Tire Cleaner. See the Cleaning
chapter for more information.
Anti-lock brake system (ABS)
This vehicle is equipped with an anti-lock braking system (ABS). A noise
from the hydraulic pump motor and pulsation in the pedal may be
observed during ABS braking events. Pedal pulsation coupled with noise
while braking under panic conditions or on loose gravel, bumps, wet or
snowy roads is normal and indicates proper functioning of the vehicle’s
anti-lock brake system. If the vehicle has continuous vibration or shudder
in the steering wheel while braking, the vehicle should be inspected by
an authorized dealer.
