My clutch pedals feel like a rock pushing it in. It's takes a lot of pressure and when it's coming out does not feel smooth. I do have the ACT Extreme clutch but it was not anywhere near this hard to push in when I first got it. I replaced the clutch slave cylinder with one from O'Reilly's, that's when it started. Do you all think that could be the problem? Would have a cheap SC take more effort to push it in?
