So the past couple weeks, it seems that my clutch pedal had got softer or non-existent since the last time I asked assistance when my car wouldn't start.

Flooding issue thread.

So I come here again asking your help guys, this is my only way around to work so I need to find out what this could potentially be and where to look ASAP.

Replace the master cylinder, hose and slave cylinder all at the same time.
Probability of success is about 90%.

I would start by checking for fluid in the reservoir(if empty then fill) then check the clutch line on the top of the transmission, then look for a leak near the bottom of the transmission where it meets the engine, if you have someone to assist you pump the clutch and see if the other individual can find a leak while pumping the clutch, does it build pressure when pumping the clutch?

Where is the reservoir located? And I will give that a shot first.

Both of these clyinders located on the transmission?

Oh oh.

The master is on the firewall, connected to the pedal.
The slave is on the transmission, pushing on the throwout lever.
The hose connects the two.

The parts aren't expensive and there's an excellent chance they fix your problem in under an hour.

if your clutch master cylinder reservoir is low and you cannot find any evidence of it leaking, it is leaking under the dash, and running under the carpet.

As said, it's most likely the clutch hydraulics. If you don't mind spending the extra time, you can replace the slave cylinder first. It's the mostly likely to wear out. If that doesn't fix the problem, replace the master. This is more work but if it is the sale cylinder you'll only have to replace the one part.

I personally just did both my master and slave as well as replacing the line with a SS one this spring. Made a world of difference for the feel of the clutch.

I would do them both at the same time, they are cheap and easy to replace, no sense making two trips to the parts store.

these questions lead me to believe that just topping of the reservoir, once you find it, will fix the issue...

it shouldn't leak. if it does something is wrong

Ummm well yeah...

I always try to do the entirety of a hydraulic system at one time because the truly time consuming part is bleeding, so do everything and only bleed once.
Pfsantos shows how inexpensive the parts are and remember, as one seal in a system starts to go, it spreads debris throughout and abrades all the other seals. If you replace say, just the slave, it's almost inevitable the master will soon follow and you'll be back in there anyway, so just slay the beast in one whack.

Well thanks everyone to help! I feel like a complete idiot, I finally found the reservoir and in-fact, it was empty...

So I added the fluid and bleeded the cylinder to be safe and she is back on the road again turning heads.

Thanks again everyone!

Brake fluid does not evaporate, so it must have leaked out.
Now that you have fluid in the system I'd take a good look at the back of the master where it comes through the firewall, that's a common leak site and hard to see because of the insulation.

Well, it only took you two weeks to find it.

I actually found it sooner, I just forgot to report back. :P
