Brake linings for trucks are primarily categorized based on the material they are made of. Here are some common types of brake linings used in trucks:

Non-Asbestos Organic (NAO): NAO brake linings are composed of a mixture of organic materials such as rubber, glass, and resins. They are known for providing smooth and quiet braking performance. NAO linings are lightweight, offer good heat resistance, and produce minimal brake dust. However, they may wear faster than other types and are not suitable for heavy-duty applications.

Semi-Metallic: Semi-metallic brake linings contain a combination of organic materials and metal fibers or powders. The metal content, typically steel or copper, enhances the durability and heat dissipation capabilities of the linings. Semi-metallic linings are commonly used in heavy-duty applications and provide excellent braking performance across a wide range of operating conditions. They can withstand high temperatures but tend to produce more brake dust and may be noisier compared to NAO linings.

Ceramic: Ceramic brake lining are composed of ceramic fibers, filler materials, and a bonding agent. They are known for their superior heat resistance, low noise characteristics, and extended lifespan. Ceramic linings offer excellent braking performance, especially at high temperatures, and generate minimal brake dust. They are often used in high-performance trucks or vehicles that require consistent and reliable stopping power. However, ceramic linings are typically more expensive than other types.

It's important to note that the availability of specific brake lining types may vary depending on the manufacturer, truck model, and regional regulations. When selecting brake linings for a truck, it's advisable to consult the vehicle's manufacturer recommendations and consider the intended application and operating conditions to ensure optimal braking performance and safety.
