I agree. I think most people ignore the last steps RJM include that deals with tuning the clutch pedal. Your master cylinder probably blew due to improper placement/adjustment of the two sensors on the pedal. Those sensors control how much clutch fluid is allowed into the master cylinder and if screwed on at the wrong depth, the master cylinder will have an improper amount of fluid in it, which will cause the already weak mechanism to prematurely fail.

What? They're not sensors, they're switches. They have nothing to do with the master failing. Incorrect adjustment of the master pushrod is what causes it to fail. Pushrod has to be square to the bore of the MC. If it's at an angle, it causes premature wear of the mc seals.

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.

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.

You are absolutely Correct Jsolo. The push rod was at an angle after I made a few adjustments on the dial (not the brown/blue switches) for the pedal engagement. I was lucky the stock clutch was not damaged and has 40k miles and still running strong. Fingers crossed.
