Hopefully a PET owner can help me out...

I need the part number for the fittings that connect up to the ends of the rubber (or stainless) flexible brake lines. I need the number for the front and rear sets (2 per brake).

I've had a new set of stainless lines for quite a while and it appears that they're too small to thread onto the fittings. Its pretty weird...my guess is that the PO had some stainless flexible lines custom made and switched out to a US-style fitting? The old stainless lines have to go...they're pretty crusty.

Just sent you email with relevant PET pages. Hopefully I have the correct email address!

Very interesting Jim. Thanks for the info. I guess that my car had some adapters made...as the flex lines appear to connect directly to the hard lines on the PET parts diagrams.

I'll take some pictures tonight for anyone that might be interested.

Are you talking about the fittings on the hard lines? S shape I think on the front and a little longer on the backs.
I replaced these lines on my car during the renovation. The new lines were pretty reasonable price. I may have kept some of the old parts if you need them. I think on some I just cut the metal line and crimped it over and used it as a cap on the caliper untill I rebuilt them and put them back on the car. I usually don't throw stuff like that away since sooner or later someone will need it! Since your changing out your trailing arms are the old lines the same as the new ones?

Let me know how I can help.
Maybe post a picture or cut and paste the Pet diagram to clarify.

On most cars including Porsches the hard line does attach directly to the flex line at a bracket of sorts. 911s have a steel tab mounted directly to the strut a few inches above the ball joint mount. The flex line goes in one side and is attached directly to the hard line. There is a spring clip that fits into a slot on the lines that holds the whole shooting match in place. The back is similar except it mounts to the control arm. The spring clips are pretty standard and can be sourced just about anywhere. IMO if you have not replaced the clips, you should when next you have the lines apart.

Well, once again I find something on my Porsche that doesn't follow the standard. I have the steel tabs on the strut, and my lines go through those. But the spring clips hold an adapter fitting in place that is separate from the flex line. It probably came with the flex line that the PO purchased and installed. The old flex lines won't connect up to the hard lines directly (bigger threads and a different thread pitch on the adapter and flex line itself.

So the issue I had was with *new* stainless steel flex lines not fitting on these -adapters-. I'm pretty sure they'll work fine going directly onto the hard lines (no adapter needed).

So Josh, are you buying new hard brake lines? I guess that's the strightforward solution; however, I vaguely recall someone mentioning building their own.

Gonna try to make my own.

Good luck, Josh. I tried this, but had problmes finding the right flaring tool. The bubble flare on Porsche brake lines is not too popular here in the US, as most stuff tense to be double flared. I ended up saying "screw it" and just bought new hard lines because I was sick of looking for the right tool.

On Pelican, some have bought generic straight VW lines which apparently have the right fittings already. They simply bend the lines to shape...no need to cut, flare, etc.

That's what I'm hoping that I'll be able to get away with...otherwise I'll end up buying the factory parts.
