Disclosed is a brake master cylinder configured to sense a variation in magnetic flux in accordance with operation of a piston installed with a magnet, and thus to control activation of brake lamps. The brake master cylinder includes a cylinder body connected to a booster, first and second pistons to reciprocate in the cylinder body, a Hall sensor installed at an outside of the cylinder body, to sense operation of the pistons, for control of activation of brake lamps, a coupling shaft formed at an end of the second piston facing the first piston, and a magnet ring assembly installed at the coupling shaft such that the magnet ring assembly faces the Hall sensor. The magnet ring assembly includes a bushing centrally formed with a fitting hole to receive the coupling shaft, and a ring-shaped magnet fitted around the bushing, to exert magnetic force on the Hall sensor.
