NOTICE
When installing each brake hose onto the hy-
draulic unit brake pipe joint (four locations),
make sure that the brake pipe "a" touches
the projection "b" on the joint.
TIP
Except for the brake hose (front brake master
cylinder to hydraulic unit brake pipe joint), each
brake hose is color-coded to its corresponding
projection on the hydraulic unit brake pipe joint
(three locations); therefore, be sure to match the
paint colors "c" and "d".

ABS (Anti-Lock Brake System)
EWA23P1007
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 master cylinder reser-
voir or brake fluid reservoir. Water will sig-
nificantly lower the boiling point of the
brake fluid and could cause vapor lock.

NOTICE
Brake fluid may damage painted surfaces
and plastic parts. Therefore, always clean up
any spilt brake fluid immediately.
8. Bleed:
• Brake system
Refer to "BLEEDING THE HYDRAULIC
BRAKE SYSTEM (ABS)" on page 3-15.
9. Check the operation of the hydraulic unit ac-
cording to the brake lever and the brake ped-
al response. (Refer to "HYDRAULIC UNIT
OPERATION TESTS" on page 4-71.)
ECA14770
NOTICE
Always check the operation of the hydraulic
unit according to the brake lever and the
brake pedal response.
10.Delete the fault codes. (Refer to "[D-1] DE-
LETING THE FAULT CODES" on page
8-129.)
11.Perform a trial run. (Refer to "TRIAL RUN" on
page 4-75.)

HYDRAULIC UNIT OPERATION TESTS

The reaction-force pulsating action generated in
the brake lever and brake pedal when the ABS
is activated can be tested when the vehicle is
stopped.
The hydraulic unit operation can be tested using
the following two methods.
• Hydraulic unit operation test 1: this test checks
the function of the ABS after the system was
disassembled, adjusted, or serviced.
