Electromechanical braking system with electrical energy back-up

An electromechanical braking system (30) is provided that includes an electromechanical brake actuator (44) for converting an electrical drive signal into mechanical energy to effect braking on a wheel (36) of a vehicle. The electromechanical brake actuator (44) is operative based at least in part on a DC supply voltage typically provided by a main supply source (60L,60R). The system further includes an electrical energy back-up system (64,66) which capacitively stores electrical energy and provides the stored electrical energy as the DC supply voltage in an absence of the main supply source (60L,60R).
