Correction Pat, you picture a tower brace, not a strut brace.

Another correction.  The purpose of a tower brace is to divide a tower
deflecting force on the outside tower between both towers.  To acomplish
this as an equal division, the brace assembly including fastnings to the
towers must be an order of magnitude stiffer than are the towers.  Yours is
questionable, inasmuch as the bar is several inches above the elevation and
several inches ahead of the applied force.  Column stiffness is seriously
degraded by the introduction of any bending force.

You should flush your brake fluid, looks like panther piss.
