Vehicle brake system

The present disclosure relates to a vehicle brake system comprising: a first fluid pressure generating device for generating a fluid pressure according to a brake operation amount; a second fluid pressure generating device for generating fluid pressure by moving the piston with the electric actuator; and a switching valve switchable between a first state allowing communication between the first fluid pressure generating device and the vehicle behavior stabilizing device and a second state allowing communication between the second fluid pressure generating device and the vehicle behavior stabilizing device. In addition to the control device placing the switching valve in the second state when an abnormality occurs including that the second fluid pressure generating device cannot generate fluid pressure, the control device places the switching valve in the second state during execution of the automatic braking control, and places the switching valve in the first state when a predetermined abnormality occurs in
