Doesn't the primary push secondary via hydraulic pressure? My thinking
is that they do. If so, my official answer is "no".    :)

FWIW, in my case I was pushing harder/further than normal likely
causing flex lines to bulge. It's possible other parts were similarly
involved.

Maybe my "thud" was something in pedal linkage bumping, or secondary
piston bumping stop screw on MC?
