What are the material use to make brake shoes?

Brake shoes are typically made from a combination of materials, including cast iron, steel, and composite materials. Cast iron is commonly used for its durability and ability to withstand high temperatures, while steel provides strength and structural integrity. Some modern brake shoes incorporate friction materials like organic compounds, semi-metallic materials, or ceramic composites to enhance braking performance and reduce noise. These materials are selected based on their ability to provide effective friction and heat dissipation.
