What symptom can brake drum appear broken?

The brake drum is hot. Under normal circumstances, using the brake for a long time will cause the brake drum to be hot. If it is not used for a long time, it means that the brake drum may have local friction failure.

If the brake drum is broken, the following symptoms will occur:

The brake fails; when braking, the brake drum makes an abnormal noise; the brake is jammed and does not return; the brake cannot return and the pedal cannot automatically spring back, so it needs to be hooked back with the foot or pressed twice to spring back. The brake becomes soft, and the brake is pressed to the end, which is much longer than the normal braking distance. When parking, the direction deviates and the brake deviates. At this time, the brake drum may be broken and need to be replaced.
