OEM Automotive Excellency Advantages of semi metal brake pads: 1) It is very stable below the conflict coefficient. No thermal degradation, good thermal stability; (2) Good wear resistance. Its service life is 3-5 times that of asbestos friction material; (3) It has good conflict performance under high load and stable conflict coefficient; (4) It has good thermal conductivity. The temperature gradient is small. Especially suitable for small disc brake products; (5) Low braking noise.OEM Automotive Excellency website:http://www.zlbrake.com/automotive-excellency/
