Heavy-duty truck brake drums are typically made from cast iron or aluminum. They operate on the principle of friction, wherein brake shoes press against the inside of the drum to slow down or stop the vehicle. According to TruckingInfo, understanding the material composition is crucial, as different materials affect heat dissipation and performance under load.
| Material | Heat Dissipation | Weight | Cost |
|---|---|---|---|
| Cast Iron | Excellent | Heavy | Moderate |
| Aluminum | Good | Lightweight | High |
