Rob Wolfe:  

I have the in flight adjustable rudder pedals and if I recall, the torsion
springs apply a force to the pedal arms pushing them forward in order to
maintain tension on the cables.  The springs do not act on the pedals directly. 
When the arms are pushed forward (in plane reference) the pedals themselves tend
to stay upright or even swivel towards the pilot due to the brake cylinder.  The
brakes will not inadvertantly apply because the master cylinders are not seeing
enough force to overcome the internal spring.  You need the pedal arms to have
spring tension like this in order to keep slack out of the rudder cables.
    However, I found the factory springs tended to cause binding between the
pedal arms and the rod they ride on.  White grease didn't help enough so I
removed these springs.  I am going with the spring setup from the standard
rudder pedals.  A hardware store screen door spring is attached to each pedal
(drill a hole in the pedal) and the opposite ends are attached to a bracket on
bonded to the firewall.  No trace of binding anymore.
