1. Operate the brake.
2. Check:
l
Front brake pad
Wear indicator grooves “a” have almost dis-
appeared
→
Replace the brake pads as a
set.
Refer to “FRONT BRAKE” on page 4-15.
CHECKING THE REAR BRAKE PADS
The following procedure applies to all of the
brake pads.
1. Operate the brake.
2. Check:
l
Rear brake pad
Wear indicator groove “a” has almost disap-
peared
→
Replace the brake pads as a set.
Refer to “REAR BRAKE” on page 4-25.
CHECKING THE FRONT BRAKE HOSE
1. Check:
l
Brake hose “1”
Cracks/damage/wear
→
Replace.
2. Check:
l
Brake hose holder “2”
Loose connection
→
Tighten the holder bolt.
WARNING
Use only the designated brake fluid. Other
brake fluids may cause the rubber seals to
deteriorate, causing leakage and poor
brake performance.
Refill with the same type of brake fluid that
is already in the system. Mixing brake fluids
may result in a harmful chemical reaction,
leading to poor brake performance.
When refilling, be careful that water does
not enter the brake fluid reservoir. Water
will significantly lower the boiling point of
the brake fluid and could cause vapor lock.
CAUTION:
Brake fluid may damage painted surfaces
and plastic parts. Therefore, always clean up
any spilt brake fluid immediately.
NOTE:
In order to ensure a correct reading of the brake
fluid level, make sure the top of the brake fluid
reservoir is horizontal.
CHECKING THE FRONT BRAKE PADS
The following procedure applies to all of the
brake pads.
A. Front brake
B. Rear brake

3. Hold the vehicle upright and apply the front
brake several times.
4. Check:
l
Brake hose
Brake fluid leakage
→
Replace the damaged
hose.
Refer to “FRONT BRAKE” on page 4-15.
CHECKING THE REAR BRAKE HOSE
1. Check:
l
Brake hoses “1”
Cracks/damage/wear
→
Replace.
2. Check:
l
Brake hose holder “2”
Loose connection
→
Tighten the holder bolt.
Loose or open holder
→
Fasten properly.
3. Hold the vehicle upright and apply the rear
brake several times.
4. Check:
l
Brake hoses
Brake fluid leakage
→
Replace the damaged
hose.
Refer to “REAR BRAKE” on page 4-25.
BLEEDING THE HYDRAULIC BRAKE
SYSTEM
WARNING
Bleed the hydraulic brake system whenever:
the system is disassembled.
a brake hose is loosened, disconnected or
replaced.
the brake fluid level is very low.
brake operation is faulty.
NOTE:
l
Be careful not to spill any brake fluid or allow
the brake master cylinder reservoir or brake
fluid reservoir to overflow.
l
When bleeding the hydraulic brake system,
make sure there is always enough brake fluid
before applying the brake. Ignoring this pre-
caution could allow air to enter the hydraulic
brake system, considerably lengthening the
bleeding procedure.
l
If bleeding is difficult, it may be necessary to let
the brake fluid settle for a few hours. Repeat
the bleeding procedure when the tiny bubbles
in the hose have disappeared.
1. Bleed:
l
Hydraulic brake system
a. Fill the brake fluid reservoir to the proper level
with the recommended brake fluid.
b. Install the diaphragm (brake master cylinder
reservoir or brake fluid reservoir).
c. Connect a clear plastic hose “1” tightly to the
bleed screw “2”.
d. Place the other end of the hose into a con-
tainer.
e. Slowly apply the brake several times.
