Yes or no for daily driver?
Searching the archives reveals very much controversy but no pictures that I could find.
I can't simulate up/down, but don't like the way it flexes when turning wheel full left and right. (Only front left so far.)
Anyone got pictures of routing (and flexing) front braided stainless brake flex lines?
Thanks.

Denny,

Here is mine I did the winter of 2023. Hope it helps.
It has not rubbed or caught on anything. Been on a couple of PCA road trips with them. I don't race so I could not tell you on that.

Always. One of the first mods I do on all my cars. Stronger if any road debris like a tire gator hits then, don't swell internally and construct iike rubber lines do, don't flex out under pressure so better braking feel and firmer pedal.

Here's a photo of old original brake lines from an 81 Euro S - look at the inside orifice diameter vs the new stainless lines. Look closely as there more black rubber inside the reinforcement section.




For hose andle and routing, here you go. I find you need some angle once the banjo bolt is tightened or the line is pulled too tight at full lock.

I don't think you your brake lines installed correctly. The stainless lines should mirror the routing of the OEM line which makes an "S" journey between the brake caliper and chassis. The S allows for the line to stay high and out of the way and still recoil when turning inward.

Here are my stainless lines installed with reused protective coil from the OEM line.

This is the problem, when I route them like this, they pull really tight and nearly kink when turned lock to lock.

We sell hundreds of sets. Zero issues

Thanks everyone for the replies.
What I did was connect the banjo end first, oriented as was the factory fitting. Then quickly get the other end in place and tightened to stop the dripping and minimize mess. Upon lock to lock check, it looked like this and I didn't like it.





Then I took the body connection back apart and rotated the hose in the fitting to find a more natural flex and now it looks like this.



It is going to stay this way unless someone tells me differently.

Cheers,

Michael you are correct. Here is how they ended up installed.

I have installed SS brake lines on almost every 928 I've owned since 2001. I also always re-utilize the protective coil as an additional guard against rubbing or whatever. Replacing original with SS brake lines is among the cheapest upgrade that a person can do to add stopping power to their braking system. I have never to this date had ANY issue with any set of SS brake lines that I have ever installed.

Denny in the pictures you have the brake line twisted and as a result it is under tension.
your line should be hand formed and should be able to follow the same profile as the original.

NOTE the line may seem tight while the wheel is turned all the way, you might be missing the rack stop collars .

AND the lines you have should be checked for the correct length.
Once the weight is on the wheels then the lines will have plenty of flexibility

Thanks Stan. I will uninstall and juxtapose form with original and reinstall.
Not sure what Roger sells, but they were apparently not in stock (what does available for pre-order mean?) so I bought >>>Techna-Fit <<<.
The front ones are a little shorter by less than an inch.

Mrmerlin

If the lines you got are shorter then all of my info may not work for you,
you are the smartest man in the room now

I will post results in a bit. Just had hernia surgery yesterday so had better lay low for spell.

For what it's worth I fitted a set 20 years ago, not had to think about them since

Many moons ago [20+ years] there were concerns about these lines and their longevity but the irony was rubber brake lines do last forever either. The stocck items probably have a life of 20 years and then need pre-emptive replacement or so I rate them.

I have had these things on both my 928's - the current ones were fitted to my GTS after acquisition way back in 2006- no issues to date - got them from Roger. Goodridge make them as I recall. Changed the brake fluid a week ago and never even thought to take a cursory look at them [probably should have though]!
