Close ups of the working ends.

The adjusting nut is quite long, with a rounded end to fit the receptacle on the brake actuating lever.

The end of the rod is more or less hemispherical, with a polarization nub.  You're viewing the nub head-on in this shot.
The link rod was rotated 90º.

The polarization nub can be seen from the side now.
The end of the rod, w/nub, as it fits in the actuating cam receptacle.

When you swing the rod 90º to its working position, the nub is engaged in the cam slot, preventing the rod from freely rotating when you turn the adjusting nut.
