Claim:
A bicycle hydraulic brake device comprising: a housing having a master cylinder; a master piston movably mounted in the master cylinder; a brake operating member movably coupled relative to the housing to move between a rest position and a brake actuating position and to move the master piston in the master cylinder in response to movement of the brake operating member to the brake actuating position; and an adjustment mechanism operatively coupled between the brake operating member and the master piston to adjust the rest position and a free stroke of the brake operating member with an initial travel position of the master piston remaining unchanged, the adjustment mechanism including a first adjustment member that adjusts a length of the free stroke and a second adjustment member that adjusts the rest position of the brake operating member without changing the length of the free stroke, the first adjustment member including a knob that is rotated to adjust the length of the free stroke, the second adjustment member including a shaft that is rotated about a longitudinal axis to adjust the rest position of the brake operating member, and the knob being coaxially supported at a free end of the shaft.
