A bicycle hydraulic brake actuation device includes a hydraulic master cylinder housing having a bore, a lever, a master piston and an adjuster. The lever is pivotally coupled to the hydraulic master cylinder housing for movement between an at rest position and a brake engagement position. The master piston is disposed within the bore and having an adjustment end. The adjuster is operably disposed between the adjustment end of the master piston and a portion of the lever. The adjuster is movable between a plurality of adjustment positions relative to the adjustment end such that with the lever in the at rest position, movement of the adjuster between the plurality of adjustment positions moves the master piston between a corresponding plurality of adjustment positions along an axial length of the bore.
