Very Very Stiff Clutch Pedal
I am currently in the process of bringing an FD back to life, and I came across a weird problem. I purchased this vehicle a couple months ago, and I just installed a stainles clutch line, as the vehicle did not have one when I purchased it. So I bled all of the brakes and the clutch (using speed bleeders on all), and after I close the bleeder on the clutch slave cylinder, I go in the car to test the clutch and brake pedals. The brake pedal felt firm like it was supposed to...The clutch pedal on the other hand felt as stiff as the brake pedal. I will admit I am relatively new to FDs, but I can't imagine that the clutch pedal is supposed to be THAT stiff. I tried searching but came up with nothing similar to my situation.
The previous owner informed at the time of purchase informed me that the clutch was either the stock clutch or a stock looking replacement, if that helps any....

i agree with seven. sounds like the guy wasn't really sure what he was putting in it. My clutch is firm not really stiff. Its sensitive as all hell. I actually stall out a lot or jump when I start in first its so touchy, pretty embarrassing especially since I'm the only FD in the area and it makes me look like a newb lol.

The type of disc won't have much effect on the pedal effort. The disc will effect the clutch engagement while the pressure plate will effect the pedal effort (i.e. a heavy duty pressure plate will create more effort).
lnbrown5981, did you actually start the car and feel the pedal pressure while driving or were you just testing it with the car off sitting still after the bleeding procedure?

i dont know what you guys consider stiff, but never in my life have i experienced a stiff pedal.
My friend has a 750hp subaru with stage III single plate.
My car has the ACT-Street/Strip.
While its "firm" its certainly not that stiff....I think the problem most people have is the on/off feeling of a heavy clutch where they can't slip it. I've never actually felt a pedal that was too hard to push down. Maybe its because I squat 500lbs.
So, if you pedal is really that rediculously stiff then maybe there is a problem? lol

I hope that's the case. Cause if I put some *** into, I can get the pedal to move about 4-6 inches, but it kinda feels like I might be breaking something, like there's a basketball behind the pedal.

^WTF
I removed the inspection plate and it appears as though the release bearing isn't moving much as the clutch pedal is pressed. Meanwhile the pedal is still barely moving. The clutch fork appears to be intact btw.

people constantly label flywheel and pressure plate as a 'clutch' this is false. a actual clutch disc has very little to do with pressure required to push in the peddle if any difference.
a heavy duty pressure plate will cause heavy peddle feel, this is normal with a hd pp

IMO, it is unlikely that the stiffness is being caused by the master cylinder. The cylinders move a lot, and, as such, would tend to be "notchy," or lock up completely (* see below). Stiffness, such as you are describing, is much more likely to occur in the bearing of a rotating shaft, i.e., the clutch fork pivot. IMO, there is very little inside the bellhousing to cause this feeling, except for a binding fork, or something bottomed out or assembled wrong.
*If the slave cylinder were "locked" or bound up, that would make the pedal feel "as stiff as the brake pedal," as you described. The only pedal movement would then be coming from pedal, master, and clutch line flex.
Did you use the pedal at any time to bleed? Did it move freely at that time? If so, the stiffness is not a master cylinder problem.
