PURPOSE: A master cylinder of a vehicle brake is provided to simplify the structure of a brake pedal by removing a brake switch by integrally forming a pedal detection sensor with the master cylinder. CONSTITUTION: A master cylinder(600) of a vehicle brake includes a cylinder body(610), a first piston, a second piston, and a spring. The cylinder body is connected to a booster generating the boosting power. The first and second pistons are installed in the cylinder body, are moved by the power which is transmitted from the booster, and transfers hydraulic pressure toward a wheel of a vehicle. The spring is installed in the cylinder body, and is compressed by the movement of the first and second pistons. The cylinder body includes a hall sensor(800). The hall sensor controls the lighting of a brake lamp by sensing the relative motion of the spring. |
