An electrically actuated aircraft brake and method characterized by the use actuator modules which can be easily and quickly replaced as a unit. Quick and easy replacement of the actuator modules can be effected without disassembly of the overall brake and wheel assembly. Accordingly, brake manufacturing, repair costs, overhaul, parts stocking and maintenance costs and requirements are minimized and/or greatly simplified compared to integrated brake designs used in the prior art. Also, a malfunctioning actuator module on an aircraft can be replaced and preferably quickly enough to allow the aircraft to remain in scheduled service and/or with a minimum of downtime.
