Braking System Design
The hydraulic system that operates
the brakes has two separate circuits.
Each 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.
Brake Wear Indicators
All four brakes have audible brake
wear indicators.
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 for
the brakes to occasionally squeal or
squeak when you apply them.Anti-lock Brakes (ABS)
The anti-lock brake system (ABS)
helps prevent the wheels from
locking up, and helps you retain
steering control by pumping the
brakes rapidly, much faster than a
person can do it.
The electronic brake distribution
(EBD) system, which is part of the
ABS, also balances the front-to-rear
braking distribution according to
vehicle loading.
You should never pump the brake pedal.Let the ABS work for you by always
keeping firm, steady pressure on the
brake pedal. This is sometimes
referred to as
‘‘stomp and steer. ’’You will feel a pulsation in the brake
pedal when the ABS activates, and
may hear some noise. This is normal:
it is the ABS rapidly pumping the
brakes. On dry pavement, you will
need to press on the brake pedal
very hard before the ABS activates.
However, you may feel the ABS
activate immediately if you are trying
to stop on snow or ice.

Replace the brake fluid when this
service is indicated on a maintenance
message in the multi-information
display.
Check the fluid level in the brake
fluid reservoir monthly.Always use Honda Heavy Duty
Brake Fluid DOT 3. If it is not
available, you should use only DOT 3
or DOT 4 fluid, from a sealed
container, as a temporary
replacement.
Using any non-Honda brake fluid can
cause corrosion and decrease the life
of the system. Have the brake
system flushed and refilled with
Honda Heavy Duty Brake Fluid DOT
3 as soon as possible.
Brake fluid marked DOT 5 is not
compatible with your vehicle's
braking system and can cause
extensive damage.
The fluid level should be between
the MIN and MAX marks on the side
of the reservoir. If the level is at or
below the MIN mark, your brake
system needs attention. Have the
brake system inspected for leaks or
worn brake pads.

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. It will stay on if you do not
fully release the parking brake.
If the brake system indicator comes
on while driving, the brake fluid level
is probably low. Press lightly on the
brake pedal to see if it feels normal. If
it does, check the brake fluid level
the next time you stop at a service
station (see page401).
You will also see a ‘‘LOW BRAKE
FLUID ’’message on the multi-
information display (see page81). If the fluid level is low, take your
vehicle to a dealer, and have the
brake system inspected for leaks or
worn brake pads.
However, if the brake pedal does not
feel 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 feel the brake
pedal go down much farther before
the vehicle begins to slow down, and
you will have to press harder on the
pedal.
You will also see a
‘‘CHECK BRAKE
SYSTEM ’’message on the multi-
information display (see page81). Slow down by shifting to a lower
gear, and pull to the side of the road
when it is safe. 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
Emergency
Towing on page446).
If you must drive the vehicle a short
distance in this condition, drive
slowly and carefully.
If the ABS indicator and the VSA
system indicator come on with the
brake system indicator, have your
vehicle inspected by your dealer
immediately.
