Hyundai Tucson: Braking System / Power-assist Brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
If the engine is not running or is turned
off while driving, the power assist for
the brakes does not work. You can still
stop your vehicle by applying greater
force to the brake pedal than typical.
The stopping distance, however, may be
longer than with power brakes.
When the engine is not running, the
reserve brake power is partially depleted
each time the brake pedal is depressed.
Do not pump the brake pedal when the
power assist has been interrupted.
Information
- When the brake pedal is depressed
under certain driving conditions
or weather conditions, you may
temporarily hear a noise. This is
normal and does not indicate a
problem with your brakes.
- While driving on a road with deicing
chemicals, brake noise or abnormal
tire wear may occur due to deicing
chemicals. In a safe traffic condition,
additionally apply the brakes to
remove deicing chemicals on the
brake discs and pads.
WARNING
Take the following precautions:
- Do not drive with your foot resting
on the brake pedal. This creates
abnormal high brake temperatures,
excessive brake lining and pad wear,
and increased stopping distances.
- When descending down a long or
steep hill, use the paddle shifter or
shift lever and manually downshift
to a lower gear in order to control
your speed without using the brake
pedal excessively. Applying the
brakes continuously will cause the
brakes to overheat and may result
in a temporary loss of braking
performance.
- Wet brakes may impair the vehicle's
ability to safely slow down and the
vehicle may also pull to one side when
the brakes are applied. Applying the
brakes lightly indicates whether they
have been affected in this way. Always
test your brakes in this fashion after
driving through deep water. To dry the
brakes, lightly tap the brake pedal to
heat up the brakes while maintaining
a safe forward speed until the brake
performance returns to normal. Avoid
driving at high speeds until the brakes
function correctly.
When your brake pads are worn and new
pads are required, you may hear a high
pitched warning sound from your front
or rear brakes. You may hear this sound
come and go or it may occur whenever ...
