Abstract
There is provided a disk brake that can hold a required thrust force and maintain a stop state of a vehicle without increasing complexity in the disk brake even if the disk brake is operated in a high temperature state of a brake pad and then a temperature of the brake pad is reduced. In the disk brake 1, an electric motor 8 is driven to thrust a piston 6, the piston 6 presses the brake pad 5 against a disk rotor 2, and the piston 6 is held in the pressed position, the electric motor 8 is re-driven after a predetermined time from a start of holding of the piston 6, and a driving condition of the electric motor 8 after re-driving is determined based on a change in value of a current supplied to the electric motor 8 by the re-driving.
