2004 Acura RSX rsx clutch piping

Have a problem here. Ive replaced clutch master cylinder and slave cylinder yesterday. I did this because my clutch was really hard and really low. I tried to bleed before replacing but couldnt get pressure at all. Even after replacing cmc and csc the clutch is still hard to push down but works fine. I guess the piping is bad? Is there anything else i can try? Also the throw out bearing? that bar that the slave cylinder pushes to engage clutch makes a squeek sound when fully pressed. Can it just be greased? Ive heard to remove boot and spray wd40 in there to fix the noise. Any help would be great. Thanks
