This paper studies the problems related to speeding up the truck brake system after the modification of the Zhuan 8A bogie and expounds the necessity of adopting the high mova. The braking rate, train maneuver, coupler clearance, brake wave speed are analyzed with multi-body dynamics simulation software ROSDY. The factors that affect the longitudinal force of the truck, the integrated braking distance, the adhesion of the wheelset and the influence on the longitudinal force are put forward. The reasonable range of the pressure of the brake cylinder for empty and heavy vehicles is as follows: empty car takes 6 5 ~ 85k Pa, heavy car to take 2 2 0 ~ 2 6 5 k Pa.
