I've recently replaced my stock clutch with an Action 1KS clutch. I ran it in very gently the first 700 miles, and have currently only 1500 miles on it. Clutch fluid was also changed along with the clutch.

The clutch have felt fine for a couple of weeks, but now the clutch pedal feels like it's stuck at the bottom when I shift at redline. It's only stuck for about half a second before it comes back up and engages normally. When I shift at a lower rpm the pedal feels fine. It's only at high rpm that it sticks. What might the problem be?

I put som grease on the clutch fork the other day to avoid the infamous sqeeky clutch sound. Can that have something to do with clutch being sticky?

I got a tip that it might be the main shaft not being lubricated properly when the clutch was installed. That should make the release bearing stick for a second when I pull the clutch back up. Anyone ever heard of something similar??

I supervised the install of the clutch by my local mechanic, and I dont think he put grease on the main shaft. In the helms manual, page 12-12, it clearly states that main shaft should be lubricated when changing the release bearing.

Should I consult my mechanic and demand he fix it?

 

never had that problem, but I've never swapped a clutch without lubing the hell out of the main shaft either..

 

Talked to my mechanic today, and it turns out that i did grease the main shaft after all.

Can the slave cylinder somehow cause the pedal to stick?

Just inspected the slave cylinder, and it turns out that it was a leak in it as there was a bit of clutch fluid in it. It was also feeling uneven when I pushed it in. Does this sound like a probable reason for my clutch to get sticky?

I also pushed the release fork back and forth, and it felt like the release bearing was sliding very smoothly inside the gearbox.

 

change the slave cylinder, and check the clutch master cyl. Make sure you bleed it properly. I had a similar problem before, it was fixed after that.

 

Same problem with my B16, changed out to a new OEM slave cylinder and the problem still persists, it gets worse the longer I drive it from heat, Bump for a fix

 

Found a solution

It turned out it was the clutch that wouldn't let go of the flywheel. God knows why it only occured at high rpms.

The solution was to ride the clutch real bad for a while to wear down the clutch a tad. I just put the the R in fifth gear, held the brake pedal in, reved ut up to about 2500-3000rpm and just rode the clutch for about 30 seconds. Then drove for a couple of minutes and did the same thing again.

After doing this 5-6 times the clutch now lets go of the flywheel just fine. No more stickyness .

I ran the clutch in just fine, so what caused this is probably the Action flywheel I have which probably is a couple og degree distorted . Riding the clutch helped it adapt to the flywheel better.

 

Well, I'm so not sure anymore what's causing this.

I just got back from an afternoon at the track, and the clutch started to get sticky again. It was fine for two 10min sessions, but then it got sticky again. In fact, it got so sticky that I had to pull over . Clutch pedal was stuck to the floor for 2-3 seconds at a time.

After cooling the car it works fine again, but sometimes it'll stick when I push it. I'm starting to think that it is the kevlar that just isn't meant for racing!?

I'm getting real sick of this problem. I'd hate to pull the tranny againg, just to find out again that it is the clutch that just won't let go of the flywheel.
