WARNING
The rear brake will not function properly if the connections are reversed.
• Brake hose (rear brake master cylinder to hydraulic unit brake pipe joint) "1" inlet: from the
rear brake master cylinder
• Brake hose (hydraulic unit brake pipe joint to rear brake caliper) "2" outlet: to the rear brake
caliper
TIP
• If the brake hose inlet and outlet connections are reversed on the hydraulic unit brake pipe joint, the
brake pedal will be pressed down to its full-stroke position without responding, and then it will be
pushed back slowly without pulsating when the final check on page "[D-3] FINAL CHECK" on page
8-131 is performed.
• If the front and rear brake hose connections are reversed on the hydraulic unit brake pipe joint, the
pulsating action in the brake lever and brake pedal will be performed in the reverse order when the
final check on page "[D-3] FINAL CHECK" on page 8-131 is performed.

ABS (ANTI-LOCK BRAKE SYSTEM)
Symptom Rear wheel will not recover from the locking ten-
dency even though the signal is continuously

draulic pressure (when the battery voltage is
normal).

If the malfunction is not corrected
after checking items (1) to (4), re-
place the hydraulic unit assembly.
Be sure to connect the brake
hoses, hydraulic unit brake pipe
joint, brake pipes, and coupler
correctly and securely. Check the
hydraulic unit operation.
