Traditionally, brake drums were made from cast iron due to its durability and excellent heat dissipation properties. However, advancements in materials have led to the use of alloys that offer even better performance attributes, such as reduced weight and improved thermal resistance. Contemporary designs may incorporate materials like aluminum or composite materials, which can enhance performance and longevity while reducing the overall weight of the braking system.

Additionally, the drum assembly includes brake springs, which play a critical role in maintaining the drum's effectiveness. There are typically two types of springs return springs and hold-down springs. The return springs retract the brake shoes after the driver releases the brake pedal, ensuring that they do not continuously rub against the drum, which could lead to premature wear. Hold-down springs keep the shoes in place against the backing plate, providing stability during operation.

Mechanical drum brakes have been a fundamental component in automotive and heavy machinery braking systems since their inception. Their design and functionality have evolved significantly over the years, yet their basic principles remain largely unchanged. This article delves into the workings of mechanical drum brakes, providing insight into their structure and operation.
