Abstract
An electric brake apparatus includes a brake mechanism, a parking mechanism, and a main ECU and rear electric brake ECUs. The main ECU performs re-holding control (re-clamping) of, after holding a braking force by the parking mechanism, releasing the holding of the braking force with the braking force applied or maintained and further applying the braking force, and then holding the braking force by the parking mechanism after that. In this case, the main ECU does not release the braking force on a rear right wheel until completing the re-holding control on a rear left wheel side. Alternatively, the main ECU does not release the braking force on the rear left wheel side until completing the re-holding control on the rear right wheel.
