will then return
to its home position, then the brake lever
will return to its home position again.

• Check that the brake lever returns to its
home position before the brake pedal
returns to its home position.
• If the brake pedal returns to its home
position before the brake lever does,
check that the brake hoses are connected
correctly to the hydraulic unit.
• If either the brake lever or brake pedal
returns to its home position slowly, check
that the brake hoses are connected cor-
rectly to the hydraulic unit.
• If the operation of the hydraulic unit is nor-
mal, delete all of the malfunction codes.
