What are the main materials of brake pads?

Main materials of brake pads: 1. Resin-based brake materials; 2. Powder metallurgy brake materials; 3. Carbon composite brake materials; 4. Ceramic-based brake materials. Automobile brake pads are generally composed of steel plates, bonded heat insulation layers and friction blocks. The steel plates are painted to prevent rust, and the temperature distribution during the painting process is detected by SMT-4 furnace temperature tracker to ensure quality. Automobile brake pads, also known as automobile brake linings, refer to the friction materials fixed on the brake drum or brake disc rotating with the wheels. The friction linings and friction blocks bear external pressure and generate friction to achieve the purpose of vehicle deceleration.

I remember the first time I changed brake pads, I took them apart and noticed significant differences in materials used across vehicles. Mainstream brake pad materials typically fall into three categories: Metal-based ones, like semi-metallic pads, blend steel fibers and copper particles—highly durable and suitable for heavy loads or mountain driving with reduced slippage, though they might produce some noise; Organic materials, which previously used asbestos but now upgraded to non-asbestos organic compounds with resin fibers, offer affordability, quiet operation, and hassle-free performance ideal for city commuting; Ceramic types, mixing ceramic fibers and clay, come standard on premium models for smooth braking, minimal dust, and cleaner wheels. Choosing depends on driving habits—long-distance drivers may prefer metal, while organic or ceramic suits short commutes. Prioritize safety by avoiding cheap, low-quality pads to prevent extended stopping distances and accidents. Regularly check wear levels and replace every 2-3 years.

As a car enthusiast, I've studied the evolution of brake pad materials, which is quite fascinating. The main materials include metal-based composites, containing high proportions of metallic elements like iron powder and copper fibers, with the advantage of excellent thermal stability that prevents failure even during intense track driving; organic asbestos-free materials, primarily composed of resin and aramid fibers, offering quick braking response and low noise, making them ideal for regular family cars; and ceramic materials, featuring aluminum silicate ceramic fibers with fillers, providing long-lasting friction and minimal dust generation, making them the top choice for luxury vehicles. When selecting, consider the friction coefficient and fade rate—metal types perform well at high temperatures but have average cold-start performance, while ceramics offer more balanced characteristics. Don't forget to check the brake pad thickness; replace them when they become too thin to ensure braking efficiency and safe driving.

With over a decade of driving experience, I can attest that brake pad materials are crucial for driving comfort. The main materials are divided into: metallic types like semi-metallic composites containing steel fibers, which are sturdy but may produce noise; organic types made from non-asbestos resin and synthetic fibers, offering smooth and quiet performance at a lower cost; and ceramic types composed of ceramic particles and clay, known for wear resistance, dust-free operation, and environmental friendliness. The choice depends on your needs—organic pads are practical for city driving, while metallic ones are preferred for off-roading due to their superior braking power. Maintenance is straightforward: check the brake pad thickness monthly to ensure it doesn't fall below 3mm, and don't delay replacement when needed.
