Carlisle Brake & Friction's EC23 brake block friction is rated for 23,000# axle loads and was specifically developed to exhibit high performance characteristics for the value driven operator. EC23 friction material meets the requirements of F.M.V.S.S. #121 dynamometer testing standards. EC23 was designed for severe duty hauling such as liquid tanker, grain, cement or refuse collection. This brake lining is also suited for low powered brake systems that require a more aggressive lining.
