Abstract
A brake device having an electric parking brake function, capable of appropriately performing stepwise increase control for a clamping force. A control unit including a computing circuit (20), a memory (21), and each motor drive circuit (23) of a parking brake control device (19) includes a stepwise increase control unit configured to increase the clamping force generated by brake pads (33) to a disc rotor (4) in a stepwise manner. When start of contact between the disc rotor (4) and the brake pads (33) caused by feeding of power from the parking brake control device (19) to an electric motor (43B) is detected based on a motor current from a current sensor unit (24), the stepwise increase control unit performs control for repeatedly feeding and stopping power to the electric motor (43B) to increase the clamping force in a stepwise manner in accordance with a predefined processing procedure.
