As the core component of the automobile braking system, the performance of brake pads directly affects driving safety. With the development of the automobile industry, the types of brake pads are becoming increasingly rich, and brake pads of different materials and structures are suitable for different driving scenarios and vehicle types. Understanding the classification of brake pads will help consumers and industry practitioners choose suitable products according to actual needs.
Classification by material
The most common way to classify brake pads is by material, mainly including asbestos brake pads, semi-metallic brake pads, ceramic brake pads and NAO (non-asbestos organic matter) brake pads.
Asbestos brake pads were once a widely used type of brake pad in the early days, but because asbestos fibers are harmful to human health, they have been banned in most countries.
Semi-metallic brake pads use metal fibers as the main raw material, have high heat resistance and wear resistance, and are suitable for high-performance vehicles and heavy trucks. However, they may generate greater noise and dust during braking, and cause greater wear on the brake disc.
Ceramic brake pads have been popular in recent years. They are made of ceramic fibers and special fillers. They have the advantages of low noise, low dust, and high temperature resistance. They are suitable for urban driving and users who pursue comfort.
NAO brake pads do not contain asbestos and metal components. They are made of organic materials such as glass fiber and rubber. They have smooth braking and less dust, but their wear resistance is slightly inferior to semi-metal and ceramic brake pads.
Classification by structure
Brake pads can also be divided into ordinary brake pads and brake pads with accessories according to their structure. Ordinary brake pads have a simple structure and are directly installed on the brake caliper; while brake pads with accessories integrate components such as silencers and back plates, which are more convenient to install and can effectively reduce braking noise.
Classification by use
Based on vehicle type and usage scenarios, brake pads can be divided into passenger car brake pads, commercial vehicle brake pads and racing brake pads. Passenger car brake pads focus on comfort and durability; commercial vehicle brake pads need to withstand greater loads and usually use more high-temperature resistant materials; racing brake pads pursue extreme braking performance and can maintain a stable friction coefficient at high temperatures.
Conclusion
Brake pads are classified in various ways, and brake pads of different materials and structures have their own advantages and disadvantages. When choosing, consumers should combine vehicle type, driving habits and road conditions to ensure the safety and reliability of the braking system. With the advancement of material technology, brake pads will develop in a more environmentally friendly and efficient direction in the future.
