Brake apparatus

A brake apparatus comprising:

• a brake mechanism configured to thrust a frictional member disposed so as to be able to abut against a rotational member configured to rotate together with a wheel of a vehicle, with use of a pressing member based on an operation performed on a brake pedal;
• a pressing member holding mechanism configured to thrust the pressing member by an electric motor and hold the pressing member at the thrust position;
• an estimated temperature calculation device configured to estimate a temperature of the frictional member to calculate a temperature estimated value;
• and
• a controller electrically connected to the electric motor, and configured to drive the electric motor in such a manner that a thrust force of the pressing member holding mechanism matches a target thrust force determined based on the temperature estimated value,
• wherein, when the controller is restarted after the controller is turned off, the controller drives the electric motor based on the temperature estimated value of the frictional member at said time when the controller is turned off.

• when the controller is restarted after the controller is turned off, the controller drives the electric motor in such a manner that the thrust force of the pressing member holding mechanism matches a target thrust force calculated by setting a greater thrust force than the target thrust force set according to the temperature estimated value at said time of the restart.
