So I put in a new oem master cylinder last year (OEM) from Z1. I installed everything but noticed that my pedal height was lowered and there was no way to bring it back up to the height I had it at before. It even had a weird light feel to it comparable to something like a civic, which i did not like. Fast forward to tonight where I stumbled across the old master cylinder and thought, why does the clevis look different between the two master cylinders? So out of curiosity I took the clevis out of the master cylinder in the car and compared the lengths of the old vs new clevis. I noticed the old one is longer! I think this explains why my pedal was lower. What I don't understand is why did they shorten the clevis because when I swapped the old clevis to the master cylinder in the car, it made my clutch feel like the day I got the car
It feels so much better! Stiffer, it sits higher, and the bite point is right in the middle! Does anyone have an explanation why this made a huge difference and maybe why they switched things up?

BTW...my first post

 

The clevis requires adjustment, once it's installed the pin should be FLOATING in the clevis without pressure pulling one way or the other. I'm guessing that the clevis length never got adjusted. That's why the end of the rod has quite a bit of threaded section and the knurled part behind the threads so you can grab onto it with a pair of plier to turn it to adjust the distance on the clevis, then tighten the jam nuts back up again.

 

That's the thing though I did have it "floating" with this newer clevis and my biting point was so low. Now when I put the old clevis back in the clutch is firm right after the bit of freeplay all the way to the floor. I do have it adjusted properly now and it just feels 100x better

 

Weird, well as long as it's working that's what matters.

 

For sure hopefully this helps someone in the future
