GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out and should
be inspected by an authorized dealer. If the
vehicle has continuous vibration or shudder
in the steering wheel while braking, the
vehicle should be inspected by an
authorized dealer.
Note:
Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See
E144522
See the Instrument Cluster
chapter for information on the
brake system warning light.
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Turn the engine off, shift to position
P
and apply the parking brake, and then
inspect the accelerator pedal for any
interferences. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
Hydraulic brake booster system
(Hydroboost or Hydromax)
The Hydroboost and Hydromax systems
receive fluid pressure from the power
steering pump to provide power assist
during braking.
The Hydromax booster receives backup
pressure from the reserve system electric
pump whenever the fluid in the power
steering system is not flowing. When the
engine is off, the pump will turn on if the
brake pedal is applied, or if the ignition is
turned to the on position.
The sound of the pump operating may be
heard by the driver, but this is a normal
characteristic of the system.
The reserve system provides reduced
braking power, so the vehicle should be
operated under these conditions with
caution, and only to seek service repair and
remove the vehicle from the roadway.
Note:
For Hydromax-equipped vehicles
operating under normal conditions, the noise
of the fluid flowing through the booster may
be heard whenever the brake is applied. This
condition is normal. Vehicle service is not
required.
If braking performance or pedal response
becomes very poor, even when the pedal
is strongly pressed, it may indicate the
presence of air in the hydraulic system or
leakage of fluid. Stop the vehicle safely as
soon as possible and seek service
immediately.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
Note:
When the system is operating, the
brake pedal will pulse and may travel
further. Maintain pressure on the brake
pedal. You may also hear a noise from the
system. This is normal.
The anti-lock braking system will not
eliminate the risks when:
•
You drive too closely to the vehicle in
front of you.
•
Your vehicle is hydroplaning.
