A convertible aircraft brake assembly (10) designed as original equipment to have heat sinks comprising a steel heat sink (20) aircraft brake assembly and a carbon-carbon composite heat sink (40) aircraft brake assembly. When the aircraft brake assembly is converted from one type of heat sink to the other, the conversion is accomplished with minimal changes in component parts. The conversion can be accomplished with a change in the piston bushing assemblies (18, 21) of the piston housing (14), while the torque tube (12), wheel (30), piston housing (14) and other parts can be utilized with the heat sinks (20, 40).
