In this paper, studied Measuring Equipment for Brake Test provided to test a braking distance and stability on various conditions while at stop/drive. It ensures an objectivity, repeatability and reproducibility for a brake test, which may be applied to various types of braking distance and stability tests anywhere in the world. With Measuring S/W for Brake Test mounted on the vehicle while at stop/drive, braking distance and stability were examined under conditions specified of NCAP and vehicle manufactures A and B's own test, which was available under all conditions and even harder ones to confirm this measuring S/W for brake test be applicable for any changed conditions for the future.
