Your vehicle is equipped with disc
brakes at all four wheels. A power
assist using negative pressure
generated by the engine and the
el ectric vacuum pump helps reduce
the effort needed on the brake pedal.
The anti-lock brake system (ABS)
helps you retain steering control
when braking very hard.
All four brakes have audible brake
wear indicato rs.
The
hydraulic system that operates
the brakes has two separate circuits.
Ea ch circuit works diagonally across
the vehicle (the left-front brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.
If the brake pads need replacing, you
will hear a distincti ve, metallic
screeching sound when you apply
the brake pedal. If you do not have
the brake pads replaced, they will
screech all the time. It is norm al for
the brakes to occasionally squeal or
squeak when you apply them.
Resting
your foot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their effectiveness.
It also keeps your brake lights on all
the time, confusing drivers behind
you.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their effective-
ness. Use the engine to assist the
brakes by taking your foot off the
accelerator and downshifting to a
lower gear.
Check your brakes after driving
th rough deep water. Apply the
brakes moderate ly to see if they feel
norm al. If not, apply them gently and
frequently until they do. Be extra
cautious and alert in your driving.
When
the electric vacuum pump is in
operation, it makes some mechanical
noises come f rom the engine
compartment. This is normal.
When you drive in cold weather or
thinner air at high altitude, the
electric vacuum pump operates more
f requently af ter the engine is started.

electric vacuum pump, see page . 396
