Abstract
Provided is a brake device capable of maintaining pads and a rotor in a desired positional relationship. When receiving a release request within a time period from start of execution of an application request to detection of contact between brake pad and a disc rotor, a parking brake control device inhibits execution of the release request, and executes the release request after detection of the contact between the brake pad and the disc rotor. Further, when receiving the application request within a time period from start of execution of the release request to detection of separation between the brake pad and the disc rotor, the parking brake control device inhibits execution of the application request, and executes the application request after detection of the separation between the brake pad and the disc rotor.
