    摘要: A vehicle brake system, including: a wheel brake device including an actuator including a piston, a working fluid chamber, an electric motor, and a piston moving mechanism; a working-fluid supply device; and a controller configured to execute: a normal brake control to control a hydraulic braking force to a magnitude corresponding to a braking request; and a parking brake control to cause the wheel brake device to be operated as a parking brake, wherein, in the parking brake control, the controller controls the wheel brake device to generate the hydraulic braking force at a start timing of an operation as the parking brake, controls the actuator to perform a lock operation in which the electric motor is operated to move the piston forward in a state in which the hydraulic braking force is generated, and controls the wheel brake device to release the hydraulic braking force after the lock operation.
