2009 Acura RL brake pads

Your vehicle is equipped with disc
brakes at all f our wheels. A power
assist helps reduce the ef f ort needed
on the brake pedal. The brake pedal
assist f unction increases the f orce
you apply to the brake pedal during
an emergency stop. When the brake
pedal assist is activated, the e-
pretensioners (if equipped) tighten
f ront seat belts (see page ). The
anti-lock brake system (ABS) helps
you retain steering control when
braking very hard (see page ).
Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, reduces their ef f ectiveness and
reduces brake pad lif e. In addition,
f uel economy can be reduced. It also
keeps your brake lights on all the
time, conf using drivers behind you.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.
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 the brakes after 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 in your driving.
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.

Af ter removing the right engine
compartment cover (see page ),
check the level on the side of the
reservoir when the engine is cold.
The f luid should be between the
UPPER LEVEL and LOWER LEVEL.
If not, add power steering fluid to the
UPPER LEVEL mark.
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 brake f luid level in the
reservoirs monthly.
Brake f luid marked DOT 5 is not
compatible with your vehicle’s
braking system and can cause
extensive damage.
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.
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.
To check the f luid level, remove the
lef t engine compartment cover (see
page ).
Replace the brake f luid every 3 years,
independent of mileage.

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 ).
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.
You will also see a ‘‘CHECK BRAKE
SYSTEM’’ message on the multi-
inf ormation display.
If the brake system indicator comes
on while driving, the brake f luid level
is probably low. You will see a
‘‘BRAKE FLUID LOW’’ message on
the multi-information display. 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
). The brake system
indicator normally
comes on when
you turn the ignition switch to the
ON (II) position and as a reminder to
check the parking brake. If you do
not release the parking brake, the
indicator will stay on, and you will
see a ‘‘RELEASE PARKING
BRAKE’’ message on the multi-
inf ormation display.
