Heavy vehicle brake drums are crucial components in the braking system of large vehicles such as trucks, buses, and trailers. These drums are typically made of cast iron or aluminum and work by providing a surface for brake shoes to press against, creating the friction needed to slow down or stop the vehicle. Their robust construction is designed to withstand high temperatures and heavy loads, ensuring reliable performance under demanding conditions.
