Abstract
An object of the present invention is to provide a brake apparatus that allows low-cost attachment of a stroke sensor that detects a stroke amount of a brake pedal. The brake apparatus is configured in such a manner that the stroke sensor that detects an amount of an axial stroke of a piston is disposed between one side surface of a master cylinder housing and one side surface of a valve housing, and an output of the stroke sensor is transmitted via a through-hole formed on the valve housing when being transmitted to a control unit attached to an opposite side surface-side of the valve housing.
