WARNING
The front brakes will not function properly if the connections are reversed.
• Front brake hose (hydraulic unit to front brake hose joint) "1": to the front brake calipers
• Front brake hose (front brake master cylinder to hydraulic unit) "2": from the front brake
master cylinder
TIP
• If the brake pipe inlet and outlet connections are incorrect on the hydraulic unit, the front brake
lever will be pulled to its full-stroke position without responding, and then it will be pushed back
slowly without pulsating when the final check on page "[C-3] FINAL CHECK" on page 8-117 is per-
formed.
• If the front and rear brake pipe connections are reversed on the hydraulic unit, the pulsating action
in the front brake lever and rear brake lever will be performed in the reverse order when the final
check on page "[C-3] FINAL CHECK" on page 8-117 is performed.
ABS (ANTI-LOCK BRAKE SYSTEM)
Front wheel will not recover from wheel lock even
though the signal is continuously transmitted
Symptom from the ABS ECU and the hydraulic pressure
has been released (when the battery voltage is
normal).
Check or maintenance job
• Check the brake lines for kinks and deterioration.

brake pipes, hoses and union bolts may close the
brake lines.

the brake master cylinder to the hydraulic unit and
from the hydraulic unit to the front brake calipers
are correct.
See WARNING and TIP.
If the malfunction is not corrected after checking

Be sure to connect the brake pipes and coupler cor-
rectly and securely. Check the hydraulic unit opera-
tion.
