Is there a replacement for the clutch hardline?
 

I'm in the middle of a swap, and was wondering if there was a solution to the ridiculous factory bent hardline. Is there a reason for it to be so extra? It's not in the way or super important, just one of those little details... :mad0259:

What kinda swap? Non-native motor? Most people use a recessed Wilwood master cylinder. DM me for a kit.

Alternatively you could use an adapter to make an AN hose fit the existing master

I'm pretty sure that's to compensate for firewall flexion. A short tube is more vulnerable to fatigue failure.

edit: My point is kind of buried in that fatigue article. This part gets more into the reason.

Is there a reason for it to be so extra what?

If you have to ask...

But, It's Biggerer!
A hard line will expand less than any kind of flex tubing.
Kind of have to use them on the brakes because the suspension moves significantly more and would spoon bend them right off.
The engine and trans housing moves too, but not as much. The stock length can absorb a clutch kick or two, but that will fatigue it as well and shorten the usable lifetime.

I have a K24A in it already. There's nothing wrong with the stock slave. I was just wondering why there short hardline was shaped that way.

Simple answer to a simple question.

That's precisely why many switch to stainless braided lines. Also keep in mind that the second half of clutch is also rubber.


This is just one of those things that I've never seen anyone talk about.

There a few write ups about SS braided lines vs oem rubber brake lines. The general opinion was that the rubber lines were more durable than the SS ones and the was no "loss" of pressure due to flex.

SS braided lines *are* rubber lines. No difference in properties other than abrasion resistance on the outside.
Steel lines are steel from the outside to inside, but they will expand with increased pressure too.
The difference is in the proportion of expansion, Steel / Rubber.

I always understood that stainless steel braided lines have a Teflon inner hose that is less stretchy than regular rubber hoses, and that the stainless steel braid is needed as Teflon is not as resistant to damage as rubber.

I would also imagine that this wouldn't matter for clutch as the pressures are much lower than in brake lines.

I believe the resistance to expansion in PTFE hoses is because of the stainless braid itself. Since the braid will pull against itself

I cringe a little every time I read about stainless braid for a clutch. Fully agree.

It all depends on the hose makeup not how it looks. All your high pressure hoses are going to have a stainless braid. It may be covered in rubber or exposed. It can be a type of rubber or a teflon inner. Look at the specification of the hose and make sure it is compatible with brake fluid.

Edit:
The hard line is like that because the engine and transmission moves. As stated above if it was a short line the constant flex would work harden the line and it would break.
