When the vehicle in overloading, high speed, especially in a long or steep slope, the braking force is large, and by continuous repeated brakes the temperature of the brake drum wall rises sharply, so the temperature difference between the inside and the outside wall is getting bigger, that the high temperature mechanical performance of brake drum material and brake performance will drop dramatically, which causes the longtitudial cracks in the inner drum wall into full of cracks.
