Abstract

Provided is an electric brake including: a brake mechanism configured to transmit, based on a braking request, a thrust force generated through drive of an electric motor to a piston configured to move brake pads to be pressed against a disc rotor; and an ECU for rear electric brake configured to control the drive of the electric motor, and to move, in a non-braking state, the piston to a predetermined clearance position at which a clearance between each of the brake pads and the disc rotor is a predetermined amount. The ECU for rear electric brake is configured to drive the electric motor so that a period from generation of the braking request to a start of the pressing of the disc rotor by the brake pads is a predetermined period regardless of a position of the piston at a time when the braking request is generated.
