2 hours on a g'damn 12mm nut, what a piece of shit. the edges of the nut even stripped when I'm using a line wrench, what kind of BS is that.

EDIT:

SOLUTION: TAKE MASTER CYLINDER OUT OF CAR AND SAVE BACK AND NECK! Also, unscrew the nut from the metal cylinder that locks onto the clutch pedal, as opposed to holding the rod with vice grips and trying to unscrew the nut that way.

note to self, 12mm nut has been replaced with 13mm :+
