Three is due to serious overloading, in under the action of gravity acceleration, increase the vehicle motion inertia, led directly to the brake failure.
三是由于严重超载，在重力加速度的作用下，加大了车辆运动惯性，直接导致刹车失灵。

The influence of the variation of tank's gravity centre during braking process on the brake performance of a tanker with partial load is studied in this paper.
