Brake shoes are a critical component of the braking system, used to decelerate or stop a vehicle through friction with the brake drum. Their performance directly impacts driving safety, especially under conditions of high temperature and frequent braking, making material selection and structural design particularly important.
The core material of the brake shoes is a semi-metallic formula composed of metal fibers, resin, and friction modifiers. Metal fibers (such as steel and copper) provide basic strength and thermal conductivity, resin acts as a binder to fix the particles, and the friction modifier optimizes the coefficient of friction during braking.
During braking, if the heat generated by friction cannot be dissipated quickly, it will cause the brake shoes to soften and the coefficient of friction to decrease (heat fade). This product improves heat dissipation efficiency through optimized metal fiber distribution and grooved design; in actual tests, the surface temperature decreased by 15% after 10 consecutive braking cycles. Simultaneously, anti-vibration structures (such as locating pins and springs) reduce vibration transmission during braking, and combined with an ultra-low dust formula (graphite content ≤5%), it significantly reduces the frequency of wheel hub cleaning.
