Air disc brakes are crucial components in modern automotive and industrial applications, offering superior performance and reliability compared to traditional drum brakes. As a supplier of 21487605 Air Disc Brakes, I have witnessed firsthand how the materials used in these brakes can significantly impact their performance. In this blog post, I will delve into the various materials commonly used in 21487605 Air Disc Brakes and explore how they affect the brakes' performance.
Friction Materials
Friction materials are at the heart of any braking system, as they are responsible for generating the friction needed to slow down or stop a vehicle. In 21487605 Air Disc Brakes, the friction materials are typically found in the brake pads and brake linings. There are several types of friction materials available, each with its own unique properties and performance characteristics.
Semi-Metallic Friction Materials
Semi-metallic friction materials are a popular choice for 21487605 Air Disc Brakes due to their excellent heat dissipation properties and high friction coefficient. These materials are composed of a mixture of metal fibers, such as steel or copper, and organic materials, such as rubber or resin. The metal fibers provide good heat conductivity, allowing the brakes to dissipate heat quickly and prevent overheating. The organic materials, on the other hand, help to reduce noise and vibration and provide a smooth braking feel.
One of the main advantages of semi-metallic friction materials is their durability. They can withstand high temperatures and heavy use without losing their friction properties, making them ideal for applications where the brakes are subjected to frequent or intense braking. However, semi-metallic friction materials can be more abrasive than other types of friction materials, which can lead to increased wear on the brake rotors.
Ceramic Friction Materials
Ceramic friction materials are another popular choice for 21487605 Air Disc Brakes. These materials are composed of ceramic fibers, such as alumina or silica, and a binder material, such as resin or rubber.

One of the main advantages of ceramic friction materials is their low noise and dust levels. Unlike semi-metallic friction materials, which can produce a lot of noise and dust during braking, ceramic friction materials are much quieter and cleaner. This makes them a popular choice for applications where noise and dust are a concern, such as in passenger cars and light trucks.
Another advantage of ceramic friction materials is their improved braking performance. These materials have a higher friction coefficient than semi-metallic friction materials, which means they can provide more stopping power with less pedal effort. This can result in shorter stopping distances and improved safety.
Finally, ceramic friction materials have a longer service life than semi-metallic friction materials. They are more resistant to wear and tear, which means they can last longer before needing to be replaced. This can result in lower maintenance costs and increased reliability.
Organic Friction Materials

Cast iron brake rotors are the most common type of brake rotor used in 21487605 Air Disc Brakes. These rotors are made from a cast iron alloy, which is a mixture of iron, carbon, and other elements. Cast iron brake rotors offer several advantages over other types of brake rotor materials, including high strength, good heat dissipation properties, and low cost.
One of the main advantages of cast iron brake rotors is their high strength. These rotors are able to withstand the high forces generated during braking without warping or cracking. This makes them a reliable choice for applications where the brakes are subjected to heavy use.
Another advantage of cast iron brake rotors is their good heat dissipation properties. Cast iron is a good conductor of heat, which means it can dissipate heat quickly and prevent the brakes from overheating. This can result in improved braking performance and longer service life.
Finally, cast iron brake rotors are relatively inexpensive compared to other types of brake rotor materials. This makes them a popular choice for applications where cost is a concern, such as in passenger cars and light trucks.
Carbon Ceramic Brake Rotors
Carbon ceramic brake rotors are a high-performance alternative to cast iron brake rotors. These rotors are made from a composite material that consists of carbon fibers and ceramic particles. Carbon ceramic brake rotors offer several advantages over cast iron brake rotors, including lower weight, improved heat dissipation properties, and longer service life.
One of the main advantages of carbon ceramic brake rotors is their lower weight. These rotors are much lighter than cast iron brake rotors, which can result in improved fuel efficiency and handling. This makes them a popular choice for high-performance vehicles, such as sports cars and supercars.
Another advantage of carbon ceramic brake rotors is their improved heat dissipation properties. These rotors are able to dissipate heat much more quickly than cast iron brake rotors, which means they can withstand higher temperatures without warping or cracking. This can result in improved braking performance and longer service life.
Finally, carbon ceramic brake rotors have a longer service life than cast iron brake rotors. They are more resistant to wear and tear, which means they can last longer before needing to be replaced. This can result in lower maintenance costs and increased reliability.
Aluminum Brake Rotors
