My clutch is out... Please help!

[Panda240sx]

So I jacked up my car the other day to change out my tires, and as soon as I was done, and started to drive off, my clutch started loosing pressure. I don't know why.

I had a similar problem on my Lancer, which makes me believe that I just have air in my line? But it makes me question why jacking my car up would do that? I positioned it under the driver and passenger door, was that wrong of me?

I really don't know what to do. My cars been sitting in my yard for the past 2 days now.

If someone could please explain to me my problem, or what I can do to fix it, that would be a really big help! Please take pictures if you can! I have no idea where anything is on this car... It's my first RWD car and I'm still learning...

Thank you so much!

Any leaks, res. level full? might try bleeding it before you go tearing into something bigger.

There's no leaks from what I can see, and the reservoir doesn't go down at all, and it's been about 3 days, just sitting in my yard...
