Clutch master cylinder/pedal adjustment

Have an 03GT six speed and I noticed lately that there has been a lot of play in the clutch pedal. It just doesnt have that the same amount of resistance or feel when its depressed(if that makes sense) I talked with a coworker of mine who's a mechanic by trade and he took a look at it and said it maybe the clutch master cylinder. He also mentioned that the loose feel in the pedal would only get worse.

To make a long story short I had a few questions pertaining to adjusting the nut behind the pedal. I spent an hour or so turning the rod behind the pedal but this did nothing. So back to the boards i went to search for an answer. I'm still having trouble trying to figure out how to increase the length of the rod so do I need to hold the plastic nut and break the nut directly behind it to make the correct adjustment is my question.

I also had a question about choosing the best clutch master cylinder replacement from what Ive read on the boards the oem replacement is plastic. Has anyone used any aftermarket replacements just curious to know. Also is this the type of part you dont wanna go cheap on and just get the oem replacement. In the link below Im considering purchasing the beck/arnley unit

I have also seen some by pbr and auto 7 whats the best replacement

I know that you've probably already figured this out since it was a few years ago but I am going to answer anyways just so that others that may have the same problem know how to make the adjustment on the pedal. There is actually two nuts and one tightens down onto the other which causes them to lock together. I had to use a really thin wrench that come with another tool in order to hold the other nut still so that I could brake loose the nut that you easily see. You have to remove the pin and connection to the pedal. Then you can pretty easily unscrew the connection to the pedal to get a little more distance. Just don't forget to tighten the nut back down afterwards and to leave enough threads of engagement so that it won't just fall off when you step on it. From my experience, which is limited, this is something that is typically adjusted after changing out the clutch on a vehicle. However, the vehicles that you are expected to make this adjustment on usually have a much easier means of adjustment (like lifting the clutch pedal).

All that being said, I'm not sure that adjusting this on a Tiburon is really fixing the problem. Mine didn't have very many threads left for adjustment anyways and I still have to press mine to the floor in order for it to feel like the clutch fully releases. After the adjustment it did make enough of a difference that it is drivable but I would only recommend this as a temporary fix. I believe that the master cylinder is having issues but I haven't fixed it just yet so I cannot say definitively just yet. I'll update after I get it fixed.

I plan on just replacing all of the major hydraulic clutch components (Slave cylinder, master cylinder, and flex line) since my car has 221 k-mi on it.
