Abstract
Provided is a brake controller which can be made smaller. The brake controller () has a hydraulic control mechanism (), which comprises a master cylinder () which generates a hydraulic fluid pressure on the basis of an input piston () and a control piston () that move when a braking operation is performed, motors (), and a moving mechanism () which moves the aforementioned control piston as the aforementioned motors turn, and a motor control unit () for regulating the turning of the aforementioned motors. The brake controller is characterized in that the aforementioned motor control unit () has a metal case () with a built-in control circuit, the aforementioned metal case () is affixed to the housing () of the aforementioned moving mechanism (), one end of the aforementioned case () is placed at approximately the same position as an end of the aforementioned moving mechanism () in the axial direction of the aforementioned input piston (), and the other end of the aforementioned case () is placed at approximately the same position as an end of the aforementioned master cylinder ().
