ok, i recently replaced the clutch, and flywheel in my teg. stage 1 racing exedy with a lightened type r flywheel. everything was good at first, then my pedal starteg gettin more and more spongy kind of feel. so i replaced the slave cylinder. no effect. today i replaced the master cylinder and bled the system again real good. still have the same spongy pedal problem. im not sure what else i can do to fix this. it shouldnt be spongy with a brand new racing clutch, slave cylinder, and master cylinder right?

 

 

I had some clutch problems a month ago and found this article from T-I... in your particular case (for a "squishy" or "spongy" feeling clutch):

"Air has gotten into the lines. The air won't fill the void that is needed to make the direct connection between the CMC and CSC. The air compresses and will not allow the system to disengage or the spongy feeling. Bleeding the hydraulic system can cure this."


However, from what you've stated, it seems like bleeding the line would have remedied this. I'm almost certain it is something to do with the line still. Have you checked for fluids when you move your car? Could have a break in the line somewhere...

 

I had this problem a while back on my one of my old si's.. The line hard line that connected to the line that runs to the tranny wasnt tightened all the way so it had a very slow leak

 

still having a bit of a problem. there was no leaks, i got all my pressure back in the pedal. i adjusted the pedal and free play back into spec according to the haynes manual. BUT, now with the brand new clutch, master cylinder, and slave cylinder my clutch now lets out all the way at the very top with the adjusted master cylinder. is there no happy medium?

haynes manual specs the clutch pedal heighth be 6.5 inches from the floor with 1/2 inch to 3/4 inch free play.
