How Many Days to Break in New Brake Pads?
1 Answers
New brake pads require a break-in period of approximately 200 kilometers to achieve optimal braking performance. Here is relevant information about brake pads: 1. Brake pad classification: Asbestos brake pads (mostly phased out), semi-metallic brake pads, low-metallic brake pads, NAO formula brake pads, ceramic brake pads, and NAO ceramic brake pads. 2. Ceramic vs traditional brake pads: In traditional brake pads, metal serves as the primary friction material, providing strong braking force but with greater wear and tendency for noise generation. After installing ceramic brake pads, abnormal squealing (scraping sounds) won't occur during normal driving. Since ceramic brake pads contain no metal components, they eliminate the metallic screeching caused by friction between traditional metal brake pads and their counterparts (brake pads and rotors). 3. Stable friction coefficient: Conventional brake pads use immature friction materials where excessively high friction coefficients may lead to dangerous situations like loss of steering control during braking, pad burning, or rotor scoring. Even when rotor temperatures reach 650°C, ceramic brake pads maintain a stable friction coefficient between 0.45-0.55, ensuring reliable braking performance.
