Hydraulic Pressure question

On the fly by wire aircraft is there still hydraulic pressure to the rudder, or any hydraulic pressure to any part of the plane? I wouldnt think so but I thought i would ask.

A fly-by-wire system literally replaces physical control of the aircraft with an electrical interface. The pilot's commands are converted to electronic signals, and flight control computers determine how best to move the actuators at each control surface to provide the desired response. Those actuators initially are usually hydraulic, but electric actuators have been investigated.
