Cable Clutch?

[bastarddsm]

Has anyone ever heard of a cable clutch setup for our cars. I have never been able to get my clutch to work properly, and i am tired of trying to.

Would anyone be interested in a cable retrofit kit for our cars?

i dont know if they do or dont have one but whats your problem? the whole braking/clutch system is very simple and would be a very easy fix for sure!

 

[bastarddsm]

I know it's simple but after trying everything, I am tired of having a shitty feeling clutch.
Now i'm gonna fix it once and for all

You're in for a project. Take pictures, and tell us about it when you're done.

Which will be never.

Thats kinda harsh. Why do you say I'll never get it done. It's not like its rocket science. All it is is make a quadrant that replaces the master cylinder and a cable mount that replaces the slave. I think the hardest part will be finding a cable suitable for the job. Jeez I can do Relativistic Kinematics, I think I can handle This.

If you want better feel, why would you switch from hydraulic to a cable? Cables stretch a heck of lot more than brake fluid compresses.

ps. I have a bunch of degrees in psychology but I'm still an A-hole who is disliked by many. What we know and what we can do are not very strongly correlated. I do not see your knowledge of theoretical physics as being relevant here.

Of course you do. And just maybe you can. I'm just going with the odds. Don't put too much stock in it, because I'm also of the opinion that it's folly to turbocharge non-turbo engines.
Like I said, show us when you're done.
I'm still waiting on the embedded headlights to replace the pop-ups, and the twin-turbo Eclipse to show up.

Have you tried a steel braided line yet? have you shimmed your pivot ball that connects to the clutch fork yet? have you tried to adjust your clutch pedal yet? their is still a couple more things you can do to get a better clutch feel.

I understand where you guys are coming from, but I am tired of fighting this thing. It has a brand new slave and master cylinder, and no matter what I do the clutch still engages an inch off the floor. The flywheel step height is correct. I am not really interested in thimming the pivot ball becuse that is just a band aid fix. I have allready tried the longer pushrod and it dosen't help either.

The thing is, there is a whole lot of experemental physics that comes with it. Such as my senior project of building an engine dyno.

then diagram the entire hydraulic system and modify it to work how you want it. You are better off modifiying your existing hydraulic system then trying to design a cable clutch but thats just my opinion.

You probably overlooked something somewhere from the pedal to the clutch assembly. Go through everything again one step at a time.

One of the difficulties would be the mechanical leverage needed for a cable versus hydraulic. If I remember clearly (gettin' tough nowadays!) you need at least a 8 or 9 to 1 leverage at the pedal and I don't even know what at the clutch fork, but I doubt you could just use the hydraulic actuated fork and only substitute a cable. And this is all with a stock type clutch. I can't imagine what you'd need to actuate an ACT 2600.

The point is it would be WAY more work reengineering for a mechanical clutch than getting your hydraulic system to work properly. It's a pretty basic system with just a few details so with the wealth of knowledge and experience here you should be able to get it working well.

BTW, you never did say what your problem is other than it's shitty feeling.

Well basically it engages about a 1/4" off the floor

I had the same problem for a long time. I eventually just shimmed the pivot ball and it solved most everything. You just have to make sure you shim it to the right distance. It may be a "band-aid" fix, but it is a permanent band-aid that works. My physics friends have that same irritating focus on getting things perfect and the way they "ought" to be. One thing studying political science has taught me is that in the real world "Ought" rarely happens and you'd best accept achieving the best you possibly can and be happy with that.
