Occasional brake noise is normal and often does not indicate a
performance concern with the brake system. In normal operation, brake
systems may emit occasional or intermittent squeal or groan noises when
the brakes are applied. Such noises are usually heard during the first few
brake applications in the morning; 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 a qualified service technician.
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.
If brakes do not grip well
• If you have been driving through deep water, gently apply the brakes
several times while the vehicle is moving slowly.
• Let the brakes cool if you have been using them excessively, as in
mountain driving or after several fast, high-speed stops.
• Check brake linings for excessive wear.
Hydraulic brake booster system (HydroBoost)
The HydroBoost systems receive fluid pressure from the power steering
pump to provide power assist during braking.
The HydroBoost booster includes a pneumatic accumulator that holds a
reserve of power steering fluid under pressure that will provide two or
more power-assisted brake applications in the event of power steering
fluid pressure loss. The accumulator will also deliver a limited number of
power-assisted brake applications when the engine is off.
The HydroBoost’s accumulator reserve provides reduced braking power,
and the number of stops is limited (depending on the severity and
duration of the brake applications), so the vehicle should be operated
under these conditions with caution, and only to seek service repair and
remove the vehicle from the roadway.
Under normal operating conditions, noise of the fluid flowing through the
booster may be heard whenever the brake is applied. This is normal and
should be no reason for concern.
