UBS diagram
When the brake lever is squeezed, the front brake master cylinder pressure sensor in the hydraulic
unit detects the hydraulic pressure. The ABS ECU calculates the appropriate rear brake force accord-
ing to the detected hydraulic pressure and sends a signal to the rear brake hydraulic pump. The hy-
draulic pump pressurizes the rear brake caliper using electronic control to operate the rear brake.
TIP
•
If the brake pedal is depressed while the brake lever is being squeezed, the brake pedal may feel hard
due to the operation of the UBS, but this does not indicate a malfunction.
•
If the rider squeezes the brake lever while resting their foot on the brake pedal, a vibration can be felt
at the brake pedal due to the operation of the UBS, but this does not indicate a malfunction.
NOTICE
ECA19610
• The UBS does not operate before the vehicle starts off.
• If the vehicle is stopped by operating the brake lever only, the brake force due to the operation
of the UBS will be maintained while the brake lever is squeezed. However, if the brake lever is
released, then squeezed again, the UBS will not operate.
NOTICE
ECA19620
• The unified brake system is a system to assist the brake operation. However, both the brake
lever and the brake pedal must be operated for maximum braking effect.
• Because the balance between the front brake calipers and the rear brake caliper in the unified
brake system is determined electronically, be sure to use the specified brake pads.
• Each set of brake pads should be checked individually and replaced if necessary.
