DIY - Easy clutch grab adjustment (~10 mins)

Yea, push down a bit on the clutch when adjusting the pedal to make it easier. You will definitely need to adjust the sensor afterwards, the video in the original post does a good job of explaining how you should do that.

Did anyone get absurd creaking or squeaking after this was performed? I did it when I first got my 2014, and asked my dealer about the sound, they tried to lube it, then just replaced my assembly... worth trying again? thoughts?

Hey everyone...

I removed the clutch return spring and performed this pedal height adjustment mod over the weekend.

The clutch feels a LOT better now, much more natural. I had no idea that the spring was the cause of my hatred for the clutch pedal feel.

I do have a question, though... while the clutch starts engaging at what feels like pretty close to the floor, it feels like it doesn't fully engage until almost the top of the pedal travel. I may not have noticed it before due to the spring introducing false feedback, but it seems awfully high to me, like there's very little pedal travel left at the top after full engagement.

Is it my imagination? Does this clutch just fully engage rather high in the pedal travel?

Is this adjustment affecting ONLY the pedal height, or it is altering the actual engagement/disengagement point?

I started with the pedal adjusted to exactly where @Koji_Online recommended, just a tiny bit (mm or so) below the brake pedal. When it seemed to be finishing it's grab point pretty high in the pedal travel, I adjusted the pedal just a tad higher to test, now it's maybe a mm above the brake pedal, same behavior. I haven't had any grinding or apparent slippage, I haven't smelled any burning.

Thoughts?

Because racecar! I love this mod. Still feels alittle weird because i completed it about 15 mins ago but my test drive was a blast. I wonder how it will feel in traffic tomorrow morning.

What is the longterm verdict on this car?

What method is more appropriate, adjusting the rods, or removing the pin and adjusting it that way?

The spring is only a small part of it. I posted on the clutch spring DIY as well. http://www.ft86club.com/forums/showt...11#post2016411

I tweak the pedal height every now and then to change things up (i.e., I've been down there quite a few times since the initial adjustment), and I still don't see how spinning the rod damages anything

So after a year of owning my car I finally caved and did this adjustment. I went 2-3mm above the brake pedal. The adjustment is as good as everyone said. I have been driving manual transmissions cars my entire life, and I never felt 100% confident in my driving abilities in this car because of the clutch.

After I did the adjustment (and triple checked everything) I went out for an hour long cruise to test it out. My launches are smoother, my downshifts are crisper, and all around driving feel is greatly improved. I'm glad that I waited so I could feel how this car was set up stock, but I will never go back to how it was before. This is the way the car should have come from the factory.

It doesn't. That's exactly how the procedure is specified in the service manual.

So if I press on the sensor, circled in red. The gap between the 2 blue circle will close up itself ? Is the sensor suppose to be some button that depresses when you press it ? or do I just push it while lifting the clutch pedal to close the gap where the protruding pin is ?

Also, the nut around the rod is 17mm & when I try to twist the rod around the 17mm nut the clutch pedal doesn't descend. Am I looking at the wrong nut or is my car different due to it being sold in a different country ?

This part is confusing me

[DocWalt]

There's two nuts on that switch. You need to back off the one that's visible in your picture then push the switch in until it's pressed most of the way in when the pedal is at resting height. Then you can tighten up the two nuts being sure that the switch stats in the correct location.

This is the best mod you can do on the BRZ. I've been driving MT since the '80's, but changing gears has been very uncomfortable and inconsistent since I got the car 6 months ago. The clutch engagement point was just set too high off the floor. I adjusted the rod by a scant 1.5 rotations and it's smoothed out the shifts considerably.

Thanks for the tutorial!

What Doc said.

The rod just spins in the master cylinder. It is CRITICAL that you get the switch adjusted properly so it allows the master cylinder rod to fully extend. I suspect pump-up due to improper adjustment is the reason some people have had clutch slippage issues.

I'm going to plug my DIY again here. In my not-so-humble opinion, this is the root of the issue.
