Federal-Mogul said a new offering of its Abex commercial vehicle drum brake block that meets Federal Motor Vehicle Safety Standard (FMVSS) 121 reduced stopping distance (RSD) requirements is now available through leading replacement parts distributors.
FMVSS 121 has been amended to reduce the specified stopping distance to 250 ft., a 30% reduction, for new truck tractors built on or after Aug. 1, 2011. The new Abex RSD drum brake block includes three application-specific formulations engineered to enhance overall performance while meeting the new FMVSS requirement:
RN: Premium organic, 20,000-lb. axle rating, copper-free formulation
RSM: Premium semi-metallic, 29,000-lb. axle rating, for RSD and severe service applications
RSC: Premium semi-metallic combo formulation, 23,000-lb. axle rating
According to the company, all Abex brake blocks are engineered and manufactured to Federal-Mogul’s stringent quality and performance standards and ensure superior modulus of elasticity and exceptional flexural strength for enhanced resistance to cracking.
