If the brake hose flare nut does not turn
easily, replace the hydraulic unit, brake
pipes, and related parts as a set.
TIP
• When installing the front brake hose (hydrau-
lic unit to front brake hose joint), front brake
hose (front brake master cylinder to hydraulic
unit), and rear brake hose (rear brake master
cylinder to hydraulic unit), temporarily tighten
each flare nut and brake hose holder nut first.
After that, tighten the flare nuts and then the
brake hose holder nut to the specified torque.
• When tightening the brake hose union bolt
"4", make sure that the metal part "a" of the
brake hose touches the brake hose bracket
"b".
6. Fill:
• Brake master cylinder reservoir
(with the specified amount of the speci-
fied brake fluid)
ABS (ANTI-LOCK BRAKE SYSTEM)
Specified brake fluid
EWA59C2401
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 perfor-
mance.
• When refilling, be careful that water does
not enter the brake master cylinder reser-
voir. Water will significantly lower the
boiling point of the brake fluid and could
cause vapor lock.
ECA13540
Brake fluid may damage painted surfaces
and plastic parts. Therefore, always clean
up any spilt brake fluid immediately.
7. Bleed:
• Brake system
Refer to "BLEEDING THE HYDRAULIC
BRAKE SYSTEM (ABS)" on page 3-16.
8. Check the operation of the hydraulic unit
according to the response at both brake
levers. (Refer to "HYDRAULIC UNIT
OPERATION TESTS" on page 4-72.)
ECA59C2402
Always check the operation of the hydrau-
lic unit according to the response at both
brake levers.
9. Delete the fault codes. (Refer to "[C-1]
DELETING THE FAULT CODES" on page
8-115.)
10. Perform a trial run. (Refer to "CHECKING
THE ABS WARNING LIGHT" on page 4-
75.)

HYDRAULIC UNIT OPERATION TESTS
The reaction-force pulsating action generated
in the brake levers 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.
