BRAKE SYSTEM FOR STRADDLE-TYPE VEHICLE AND STRADDLE-TYPE VEHICLE

An object is to improve mountability of a brake system to a straddle-type vehicle while considering safety. In a brake system, a mechanism portion includes a friction applying device which brakes a wheel of a straddle-type vehicle with a frictional force corresponding to a movement of an operator, an operator movement sensor which detects the movement of the operator, and an actuator which is unitized with the friction applying device. During normal braking, a control unit controls an output of the actuator based on a detection result of the operator movement sensor to change the frictional force applied to the wheel by the friction applying device. Further, when the actuator is in a non-energized state, the friction applying device applies a frictional force to the wheel.
