Abstract
A brake control device includes a brake operation member, a pressurization unit, a master cylinder unit, a connection path connecting a separation chamber and a reaction force chamber, an electromagnetic valve at the connection path, and a control device. The control device includes a specified control section configured to, when the brake operation member is operated in a closed state of the electromagnetic valve, execute activation-time control in which the pressurization unit supplies fluid to a servo chamber based on a predetermined pattern, a determination section configured to determine whether a pressure difference between pressure in the reaction force chamber and pressure in the separation chamber, is equal to or less than a threshold value, and a valve control section configured to open the electromagnetic valve when the determination section determines the pressure difference is equal to or less than the threshold value after start of the activation-time control.
