2009 Acura RDX brake pads

Your vehicle is equipped with disc
brakes at all f our wheels. A power
assist using negative pressure
generated by the engine and the
electric vacuum pump helps reduce
the ef f ort needed on the brake pedal.
The anti-lock brake system (ABS)
helps you retain steering control
when braking very hard.All f our brakes have audible brake
wear indicators.
The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the lef t-f ront 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 distinctive, 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 normal f or
the brakes to occasionally squeal or
squeak when you apply them.
Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their ef f ectiveness
and reduces brake pad life. In
addition, f uel economy can be
reduced. It also keeps your brake
lights on all the time, conf using
drivers behind you.
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.
For more inf ormation about the
electric vacuum pump, see page . Constant application of the brakes
when going down a long hill builds
up heat and reduces their ef f ective-
ness. Use the engine to assist the
brakes by taking your f oot of f the
accelerator and downshif ting to a
lower gear.
Check your brakes af ter driving
through deep water. Apply the
brakes moderately to see if they f eel
normal. If not, apply them gently and
f requently 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.

Always use Honda Heavy Duty
Brake Fluid DOT 3. If it is not
available, you should use only DOT 3
or DOT 4 f luid, f rom a sealed
container, as a temporary
replacement.
Using any non-Honda brake f luid can
cause corrosion and decrease the lif e
of the system. Have the brake
system f lushed and ref illed with
Honda Heavy Duty Brake Fluid
DOT 3 as soon as possible.
Brake f luid marked DOT 5 is not
compatible with your vehicle’s
braking system and can cause
extensive damage.The f luid level should be between
theMINandMAXmarksontheside
of the reservoir. If the level is at or
below the MIN mark, your brake
system needs attention. Have the
brake system inspected f or leaks or
worn brake pads.
Check the f luid level in the brake
f luid reservoir monthly.
Replace the brake f luid every 3 years,
independent of mileage.

If the f luid level is low, take your
vehicle to a dealer, and have the
brake system inspected f or leaks or
worn brake pads.
However, if the brake pedal does not
f eel normal, you should take
immediate action. A problem in one
part of the system’s dual circuit
design will still give you braking at
two wheels. You will f eel the brake
pedal go down much f arther bef ore
the vehicle begins to slow down, and
you will have to press harder on the
pedal.Slow down by shif ting to a lower
gear, and pull to the side of the road
when it is saf e. Because of the long
distance needed to stop, it is
hazardous to drive the vehicle. You
should have it towed, and repaired as
soon as possible (see
on page ).
You will also see a ‘‘CHECK BRAKE
SYSTEM’’ message on the multi-
inf ormation display (see page ). If you must drive the vehicle a short
distance in this condition, drive
slowly and caref ully.
If the ABS indicator and the VSA
system indicator come on with the
brake system indicator, have your
vehicle inspected by your dealer
immediately.
The brake system indicator (red)
normallycomesonwhenyouturn
the ignition switch to the ON (II)
position, and as a reminder to check
the parking brake. It will stay on if
you do not f ully release the parking
brake.
If the brake system indicator (red)
comes on while driving, the brake
f luid level is probably low. Press
lightly on the brake pedal to see if it
f eels normal. If it does, check the
brake f luid level the next time you
stop at a service station (see page
).
You will also see a ‘‘BRAKE FLUID
LOW’’ message on the multi-
inf ormation display (see page ). 77391
