Yay. It's a happy ending. Brake pedal is firm. Clutch works. And no more sticky rear calipers.
It's enough to make you tired of winning.

Change the fluid every other year. Brake fluid absorbs water from the air and that lowers the boiling point. More importantly the water will drop out of suspension and proceed to the calipers and once there will start corroding the interior surfaces.

I can bleed all 4 calipers by myself in little more time than it takes to access the calipers.
