lever is pulled to full stroke without responding and will be pushed back slowly without pulsating
when the final check in [D-6] is performed.
• If the front and rear brake hose connections are reversed on the hydraulic unit, the pulsating action
in the brake lever and brake pedal will be performed in the reverse order when the final check in
[D-6] is performed.
