What materials are brake pads made of?
2 Answers
Brake pads are generally made of four types of materials: resin-based brake materials, powder metallurgy brake materials, carbon composite brake materials, and ceramic-based brake materials. Automotive brake pads typically consist of a steel plate, an adhesive heat insulation layer, and a friction block. The steel plate is coated to prevent rust, and the coating process is monitored using an SMT4 oven temperature tracker to ensure the temperature distribution during coating meets quality standards. Brake pads can be mainly categorized into the following types: asbestos brake pads, semi-metallic brake pads, low-metallic brake pads, NAO formula brake pads, ceramic brake pads, and NAO ceramic brake pads. There is no standardized answer for when to replace brake pads, but the general replacement frequency is around 30,000 braking cycles. If you don't use the brakes frequently, they can last up to 60,000 kilometers without issues.
I've driven several cars, and the material of brake pads is indeed quite important. They are mainly divided into three types: organic, semi-metallic, and ceramic. Organic brake pads are usually made of friction materials, resin, and fibers, which are affordable but also prone to wear. Semi-metallic ones add steel or copper fibers mixed with resin, offering better heat resistance. Ceramic brake pads are even more advanced, using ceramic particles mixed with friction agents, resulting in less noise and dust during braking. Why different materials? Because friction during braking generates heat, and these materials can withstand high temperatures, preventing failure, especially during sudden braking or long drives. When replacing brake pads, I recommend checking their thickness regularly, typically replacing them every 20,000 to 30,000 kilometers. Safety first—I always remind myself not to skimp on this expense. Remember to choose materials that match your vehicle model, as mismatched ones can affect braking distance.
