Clutch Dramas - R33 Gtr

[R33GTRKid]

Hey all,

I just had a new HKS GD Max (sprung centre) twin plate installed into my 33 GTR. The shop ordered the genuine nissan release bearing specified in the clutch kit as well as the flywheel bolts, everything else is supposedly supplied.

The issue I have is that the friction point is now at the very top of the pedal travel. I complained and they first shortened the travel of the pedal and also re-bled the entire system. All this did was lower the pedal height but not change the friction point.

I took it back again and was told that the only way to change the friction point would be to shorten the slave cylinder rod, I said ok. Had my car for the day, get it back and they said we actually did not do anything, we think that shortening the rod will not work, you have to upgrade the slave cylinder to a Nismo which means you will need to push the pedal down more to shift the additional volume of oil (as it is a bigger slave, with bigger volume), which will therefore move the friction point down the pedal travel.

Does this sound right. I thought that the bigger slave cylinder would mean that you would need less pedal travel to move the clutch not more??

I am in Perth so if anyone here has the time to check it out and give me some ideas, I would really appreciate it but at the moment I am afraid to give the car any stick for fear that the clutch will slip and after spending $2750 on it I really do not want that to happen

you can lower the pedal height by adjusting the master rod on the clutch pedal in the car. also a bigger diameter slave will take more travel to push the clutch fork the same distace, (makes it lighter) but you can usally adjust this out using the master rod in the car,

very simple really,

thanks I do not want to lower the pedal height but I do want to lower the friction point closer the floor so the bigger slave diameter should do the trick then

thanks mate
