Even worse things can happen if those switches are incorrectly adjusted.
1) Premature clutch wear due to lack of full engagement
2) Difficulty in shifting due to clutch not fully releasing
Both of these can be much costlier than replacing the MC.

I couldn't think of the technical term for the "switches" but we are both referring to the same thing: the brown and blue buttons on either side of the clutch pedal travel. The top one (brown) controls the amount of fluid allowed into the mc and if it's not engaged correctly, the hydraulics will pump an incorrect amount of fluid. You're right about the angle of the mc push rod though, it does indeed to be straight or it'll cause the mc to leak. Both of these problems can cause premature failure of the mc as well as other components of the clutch.
