Technical Specifications and Operating Principles

A brake drum is a cylindrical component typically made of cast iron, which rotates with the wheel. Inside the drum, two curved brake shoes, lined with friction material, press outwards against the inner surface of the drum when the brake pedal is applied. This friction generates heat and slows the vehicle. Key technical parameters define the performance and suitability of brake drums for specific applications.

Material Science: The Foundation of Durability

The primary material for heavy-duty brake drums is high-grade grey cast iron, specifically grades such as HT250, HT300, or G3000. These materials are chosen for their excellent thermal conductivity, wear resistance, and damping capabilities.

• High Carbon Content: Provides excellent thermal stability and resistance to thermal cracking.
• Graphite Flakes: Distribute heat efficiently and contribute to the material's damping properties, reducing brake noise and vibration.
• Alloying Elements: Chromium, molybdenum, and copper are often added to enhance hardness, wear resistance, and high-temperature strength, crucial for demanding applications like heavy-duty truck drum brakes.
