Excuse me for being a little slow on the uptake; but what are we tryijng to
accomplish with the bells, whistles, and lights?  Knowing when the rudder is
fully deflected?  Knowing when the brakes are being applied?  Knowing if
we've adjusted the brake cylinder rods properly?   I haven't gotten to the
point of connecting rudder cables, but IF a "fix" is needed, isn't something
like a strong short spring which allows the pedal to continue travel a bit
beyond full rudder deflection as brakes are applied all that is required?
And it would seem that Jeff is correct; what you want is some "feel" that
the rudder is fully deflected and the brakes are being applied.

It's probably a mistake to interject here having not yet connected cables or
flown my airplane, but I was wondering, so I'll take the risk.
