Abstract: A brake device capable of appropriately releasing a pressing-member retention mechanism when a failure is detected. When a failure of one of a pair of disc brakes (31) is detected, an electric actuator (43) of the non-faulty disc brake (31) is driven to a release side in response to a release request based on a parking brake switch (18) in a case where a state of the faulty disc brake (31) is stored as a “released state” in a storage section (19A) of a parking brake control device (19). In contrast, in a case where the state of the faulty disc brake (31) is stored as an “engaged state” in the storage section (19A), the electric actuator (43) of the non-faulty disc brake (31) is inhibited from being driven to the release side even when the release request based on the parking brake switch (18) is issued.
