I have never seen or heard of any failure the likes of this.
Here is my story:
I drove all the way home yesterday and parked the car. I like to leave the car in gear when I park in order to avoid relying on my uber-reliable handbrake. With the engine shut off, I press down on the clutch pedal quickly (as I always do) to engaged first. Then I hear a pop and the clutch goes and STAYS on the floor; I have to bring it back up with my foot.

Now since the car worked fine the entire drive home, I figured it must be the clevis that disconnected or something of the sort. After I stuck my camera in there and took a shot, this is what I found:

So, it seems the threaded part of the clevis mechanism (or whatever you call it) sheared!
Looks like I'm going to have to order a whole new master cylinder?! or is there a way to repair this?

That is the CLUTCH master cylinder, not the BRAKE Master Cylinder just to be clear. I am guessing that your clutch is old and it was getting more and more difficult to press it in right? Well, until it broke and then it was real easy. ;>)

You might find some previous repair articles by searching. One method is to use a double-nut on the threaded shaft to bridge the break. This was either an extra wide nut like threaded rods at the hardware store are joined or two nuts epoxied together. A new clutch master cylinder will fix it also.

Speculation is that the throw out bearing gets hard to move because the clutch disk is worn so much and a new clutch is in your near future.

I think your break is too close to the rod end to effect any repair of the existing cylinder.

Thanx for the reply fellas. Yes yes Dave, I know it was the CLUTCH master cylinder. I felt it would obvious since I was mentioning the clutch :P

Like Tom said, the break is to close to the rod for any R&R to work. I've already ordered a new master cylinder (CLUTCH master cylinder) since mine was nearing the end of its lifetime.

By the way, is it easy to replace this thing or should I let my mechanic do it?

Thanks again everyone.

Sometimes other people do NOT know these things. My comment was for them, not you. I just wanted things to be clear for others. I trust the link to the CLUTCH master cylinder replacement will help you.

BTW, you might want to consider changing your clutch if it is that stiff to cause the rod to fail.

Well, you know where it is since you were able to take such a good photo. So, if you don't mind the body position that gets you there, the work is not too bad.
