It is obvious in this photo that the cracks on the brake disc have been very thorough, or this is one crack after another. At first, the logistics company suspected that it was the quality problem of the brake disc. Later, after troubleshooting, it learned that it was overuse of the brake. Frequent friction and high temperature led to the damage of the brake disc, which was not a quality problem.
If the picture above doesn’t explain the problem, then this picture is very obvious. After frequent work, the brake disc generates high temperature due to friction, which has burned the whole brake disc out of shape. Our most direct feeling is that the brake disc is burnt brick red.
After identification and investigation, there are three reasons for the high temperature of the brake disc:
To be honest, a greater part of the causes of these vehicles’ faults lies in the drivers’ wrong driving habits and concepts. If we want to reduce this potential safety hazard as much as possible, the most important thing is to start disc brakes from the drivers.
