We put hydraulic power braking system into practice, by this mean we have short delay time and high working pressure so that the size of the master cylinder could be small. In this case the brake is constructed easily, having less mass and much more efficient. Assume adhension coefficient was 0.8 and initial speed of braking was 20 km/h, maximum deceleration and braking distance was calculated. This study is helpful for the braking system design of racing car.
