Brake Noise

During normal operation of the brake system certain
noises may be present from time to time. Occasional

ЉgroanЉ or ЉsquealЉ noises may occur during normal
operation of the brake system which may not be indica-
tive of a problem. These noises may be heard at any time
the brakes are applied but may be more noticeable during
the first few brake applications in the morning. Moisture,
hot or cold temperature, dust, and or other debris may
also contribute to the noise condition. Repeated or con-
tinuous noises during braking may be an indication that
the brake linings are worn and in need of replacement.

Four-Wheel Anti-Lock Brake System (ABS)— If
Equipped

This Anti-lock Brake System is designed to aid the driver
in maintaining vehicle control under adverse braking
conditions. The system operates with a separate com-
puter to modulate hydraulic pressure to prevent wheel
lockup and help avoid skidding on slippery surfaces.

The system’s pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation. This is
normal.

When you are in a severe braking condition involving
use of the Anti-lock Brake System, you will experience
some pedal drop as the vehicle comes to a complete stop.
This is the result of the system reverting to the base brake
system and is normal.

Engagement of the Anti-lock Brake System may be
accompanied by a pulsing sensation. You may also hear a
clicking noise. These occurrences are normal, and indi-
cate that the system is functioning.

ABS Warning Light
The Anti-lock Brake System includes an amber warning
light. When the light is illuminated, the Anti-lock Brake
System is not functioning. The system reverts to standard
non-anti-lock brakes.
