I believe Dave Bangle told me that his aircraft was damaged due to the
problem with the standard brakes. The pilot inadvertently applied brake on
one side while only attempting to apply the rudder. As Ken points out,
there is a problem with the basic geometry in the original set up.
What Keith provides is a simple conversion kit which keeps the brake lever
at a constant angle. I checked this out pretty carefully. In the standard
set up, e.g. as you apply right rudder, the top of the pedal tilts up as the
rudder bar goes down. If you are not watching or feeling the feedback
correctly, you begin to apply more and more brake as you depress more & more
rudder.
Keith's fix keeps the the angle between rudder & brake bar reasonably
constant so that this does not happen, i.e. you don't inadvertently apply
brake. You have to consciously apply toe pressure to get the brakes to
operate. It works very well.
After witnessing a Rebel goes on its nose in front of me at NC3 while
taxiing my second favourite airplane in the world, the Super Cub, I
determined that I would only use the brakes on the taxiways or at least
until I had many hours of Rebel time on the clock. (There was never much
danger of putting the Super Cub on its nose with the heel brakes installed
in the original Cub). The Rebel
lands short enough in most situations anyway that brakes are mostly
unnecessary except while taxiing.

I believe Keith builds a neat mechanical linkage to tie the right seat
brake pedals to the left seat master cylinders to provide dual brakes.
I went with a second set of used $20. brake cylinders instead, but I
still have to buy or make another set of brake pedals.
Another issue is whether you mount the master cylinders in the manner
that MAM recommends or if you relocate the bottom mount for the cylinder
to a strong bracket fixed to the floor. The reason for that is so that
the brake pedal stands vertical and does not tilt forward as you apply
rudder pedal. There is simply no end to the ways you can customise your
bird!

*---------------------------------------------------------------------------Hi All
While looking at old messages I notice alot of talk about pedals and some
question of how to set them up. The name Keith Kinden was mentioned as
having a fix for sale. Can anyone explain the problem, what his fix is and
if its worth purchasing also how to reach him
