Abstract
There is provided a brake apparatus configured to identify a fluid leak spot while generating a braking force. The brake apparatus is configured to drive pumpto supply a brake fluid to a first fluid passage (fluid passageP, discharge passageP) and a second fluid passage (fluid passageS, discharge passageS), switch communicating valvesP andS alternately between open and closed positions more than once, and detect a brake-fluid leakage in the first or second fluid passage on the basis of magnitudes of detection values detected by hydraulic-pressure sensorsP andS during the open-close switching.
