RAPCO offers FAA-PMA approved direct replacement brake discs for Cleveland and McCauley brake assemblies. They are designed and tested to meet or exceed OEM performance and provide outstanding service life. RAPCO brake discs are forged from carbon steel billet which tightly alignes the grain structure and adds greater strength. In addition the discs are heat treated for a long service life. This is not only important for the discs, but it also helps to maximize brake lining life as well. The hardened forgings are precision machined and then plated with electroless nickel for corrosion resistance. In a final machining process, the wear surfaces of the disc receive an additional turning to assure they are true. This reduces vibration and allows the disc to rapidly transfer heat away from the lining material, resulting in improved stopping and longer service life. Then each disc is laser etched for proper permanent identification. RAPCO brake discs offer premium features at a competitive price.
