Abstract: A vehicle brake system includes a switching valve switchable between a first state allowing communication between a first fluid pressure generating device and a frictional brake and a second state allowing communication between a second fluid pressure generating device and the frictional brake. The second fluid pressure generating device generates a fluid pressure by moving a piston with an electric actuator, and has a fluid pressure supply port connected to the switching valve and an atmosphere opening port connected to a reservoir tank. When, due to a failure, the switching valve becomes a third state in which the switching valve makes each of the first fluid pressure generating device and the second fluid pressure generating device communicate with the frictional brake, a control device controls the second fluid pressure generating device to close the atmosphere opening port with the piston.
