BRAKE WARNING LIGHT
The brake system warning light
is
covered
in
the "Instrument Panel"
section.
POWER BRAKES
If
optional
pOwer
assist
is
lost because
of
a stalled engine or other
reasons, the brakes can normally still be applied with power assist
at least two times using reserve power.
The system
is
designed . to bring the car
toa
full stop on reserve
power if the brake pedal
is
applied once
and
held down. However,
the reserve power
is
partly
used
up each time
the
brake pedal
is
applied and released.
Do
not pump the brakes when brake power
assist has been lost, except when needed to maintain steering
control on slippery surfaces.
Without power assist, the car can still be stopped by pushing much
harder on the brake pedal. However, the stopping distance may be
longer, even though the brakes themselves remain fully operational.
SELF-ADJUSTING BRAKES
The brakes on this
car
(except fot the parking brake) are
self-adjusting. They have been designed
so
that
periodic brake
adjustment
is
not required.
The drum brakes adjust themselves when the brakes are firmly
applied while the car
is
moving backwards.
The disc brakes adjust themselves each time the brakes are used.
If
the brake pedal goes down
farther
than normal it may be due to a
lack of adjustment. To find out if this
is
the case, drive backward
and forward a
few
times,. applying the brakes firmly when going
each way.
See ybur dealer
if
pedal height does not return to normal,or
if
there
is
a rapid increase
in
pedal travel, which could be a sign
of
other
brake trouble.
Also see your dealer if the parking brake needs adjustment.
NOTICE: "Riding the brake" by resting your foot on the brake pedal
when not intending to brake can cause overheated brakes. This can wear
out the brake linings faster and damage the brakes themselves, as well as
waste,fuel.
DISC BRAKE WEAR INDICATOR
Front disc brakes have a built-in wear indicator
that
is
designed to make
a high-pitched squealing
or
cricket-like warning sound when the brake
linings are worn to where new linings are needed. The sound will come
and go, or be heard all the time when the wheels are rolling, but
will
stop
when the brake pedal
is
pushed down firmly. Expensive damage can
result if linings are not replaced when needed.
See also the brake checks listed
in
the Maintenance Schedule folder.
