I give up...

Andy is right, now that you mention this weird screeching noise (although it should have nothing to do with hitting your brakes) it might be the preasure plate since everything else seems good. My thoughts are you might as well replace the master cylinder now too, even if it doesn't cure your problem at least you know its good and won't be leaking anytime in the future. If that doesn't fix it (we'll see, worth a shot) then it'll be time to replace your whole clutch along with a new Mitsu throwout bearing. I suppose you could buy just a new ACT preasure plate since you already have a new disc, but I'd recomend a Centerforce Dual-Friction since its a perfect FWD clutch and is much stronger than the 2100 but no where near as harsh on your system as the 2600. We can discuss clutches some other time though if you want. I can understand you want this fixed for as cheap as possible so then the 21/2600 PP would be the best choice more than likely (but damn do I hate their clutches and constant quality problems).
