What material are car brake pads made of?
3 Answers
Car brake pads are made of the following materials: 1. Resin-based brake materials; 2. Powder metallurgy brake materials; 3. Carbon-carbon composite brake materials; 4. Ceramic-based brake materials. Car brake pads, also known as car brake linings, refer to the friction materials fixed on the rotating brake drum or brake disc of the wheel. The friction linings and friction blocks bear external pressure to generate friction, thereby achieving the purpose of vehicle deceleration. Car brake pads are generally composed of steel plates, bonded heat insulation layers, and friction blocks. The steel plates are coated to prevent rust, and the coating process is monitored using an SMT4 furnace temperature tracker to ensure the temperature distribution during the coating process and guarantee quality.
I've been driving for over ten years and have some insights into brake pad materials. Brake pads are typically made of composite materials, such as organic ones, which mainly consist of resin, rubber, and fibers. They provide quiet braking with no noise, making them suitable for daily commuting. However, they wear out quickly with frequent use and need to be replaced often. Semi-metallic materials incorporate some metal fibers, like copper or steel, offering excellent braking performance and stability during sudden stops, though they tend to be noisier and produce more dust. Ceramic materials are more high-end, made with ceramic fibers, boasting strong durability and producing less dust, which makes car cleaning easier. However, they are more expensive and better suited for those who frequently drive long distances. Different materials affect the friction coefficient, heat resistance, and performance in wet conditions. Last time I changed my brake pads, I opted for ceramic ones after considering durability and environmental factors. Now, driving feels much more comfortable. I recommend checking your vehicle's manual and matching the material to your driving habits before making a choice—don't just go for the cheapest option.
I consider myself a car enthusiast and love delving into details. There are various types of brake pad materials. Common ones include organic composite materials, primarily made of resin and glass fibers, which provide smooth and quiet braking, ideal for daily use but prone to overheating at high temperatures. Semi-metallic materials contain 30-65% metal particles like steel fibers, offering high friction coefficients and shorter braking distances, suitable for performance-oriented cars, though they generate more noise and dust, which can affect the car's paint. Full-ceramic materials use alumina ceramic fibers, featuring lightweight properties, fast heat dissipation, long wear life, and minimal dust, making them the premium choice but at a higher cost. Low-metallic materials strike a balance between the two, offering practicality. The material affects braking responsiveness—for instance, ceramic pads provide more stability during mountain road turns. When choosing, consider noise, dust, price, and ensure compatibility with the brake discs to avoid slipping issues.
