Braking system for motorcycle

A braking system (30) for a motor cycle includes first and second braking force generating mechanisms (35,36), first and second operation members (13,18), a second association mechanism (21) which supplies hydraulic pressure to one of the braking force generating mechanisms (35) when one (13) of the operation members (13,18) is operated, and a control unit (28) which controls the second association mechanism (21). When the control unit (28) detects an abnormal condition of the braking system in a state where the second association mechanism (21) is driven, the control unit (28) causes the second association mechanism (21; 44,47,49,57) to gradually reduce hydraulic pressure supplied to said one braking force generating mechanism (35) substantially toward zero.
