Here is picture of what it looks like just so you know what you are
wrenching on.

I jack up the rear end so both wheels are off the ground. Loosen your
lock nut on the brake rod. I would just keep messing with it so as you
press the brake pedal it begins to engage the brake. The manual gives
some decent guidelines but not perfect on the brake setting position
on the pedal itself. Keep in mind the brake is not stopping the wheels
but the rear end which makes the wheels not able to turn. If you can
get it set at the point where the brake just engages, then you will be
able to set the hydro to return to neutral with the brake. I hope that
makes some sense. If not just say so I will try to explain it different.
It might take some tinkering but worth taking your time.
Also make sure that all the places that pivot turn and such are free
of crud. Just follow the linkages from brake to rear end and make sure all moves
easily. 50 years worth of crud can seriously mess with your attempt
to adjust. Good Luck
