Abstract: A vehicle brake system includes: a brake device configured to apply a braking force to a wheel; and a controller configured to cause the brake device to perform an ABS operation when a slip ratio of the wheel exceeds a threshold. The ABS operation includes a decrease mode in which the braking force is decreased and an increase mode in which the braking force is increased to restore the braking force after the decrease mode. The controller determines a final target braking force that should be attained at an end time point of the ABS operation based on the braking force at a start time point of the ABS operation and determines a cycle time of the ABS operation based on a condition of a road surface on which the vehicle travels. The cycle time is a length of time in which the ABS operation is performed.
