To provide a front wheel and rear wheel interlocking brake system having a simple structure, which is capable of automatically performing brake control of the front and rear wheels on the basis of the running state of the motorcycle. A front wheel and rear wheel interlocking brake system is provided for a motorcycle in which a front wheel brake and a rear wheel brake, each being hydraulically operated, are provided on a front wheel and a rear wheel, respectively. The brake system includes a front wheel side actuator for applying a hydraulic pressure to the front wheel brake. A rear wheel side actuator is provided for applying a hydraulic pressure to the rear wheel brake. At least one operating member is operated by a driver. An operated amount detecting member is provided for detecting the operated amounts of each brake operating member. A control member is provided for receiving and calculating each of operated amounts detected by each operated amount detecting member. An outputting drive control signals to the front wheel side actuator and the rear wheel side actuator on the basis of the calculated result. In this brake system, the control member performs brake control for single brake control for singly driving either the front wheel brake or the rear wheel brake and interlocking brake control for driving the front and rear wheel brakes in accordance with a specific braking force distribution characteristic, and causes control to switch between single brake control and interlocking brake control on the basis of the operated amounts detected by the first and second pressure sensors.
