which brake hard line

[aston@ultrasw.c]

I need a brake hard line

M10-1.0 male both ends

ISO bubble flare

4.75 mm tubing

Overall length 12 - 14"

App, to eliminate the rear pressure limiting valve

Can anyone identify the part number of something suitable.

Thanks

I can make you one with new cunifer tubing & new tube nuts. Tell me how long you want it to be from bubble to bubble & i'll make it in the next day or so.

No charge whatsoever. I've learned a lot of neat fabrication ideas from the posts you've made on the forum so i'll gladly repay you with a no cost brake line. Just PM me where I should send it to.

WOW. That's outstanding.

Thank you so much.

I had no idea my posts were that interesting

I'll send a PM

No problem Chris. I'll get it made up for you this evening and send it your way.

BTW local auto parts stores have the lines pre-fabbed in various lengths. I've bought a handful of 12" pieces for making rear brake lines to connect the small Brembos to the 911 trailing arm. But that store bought line is a PITA to bend since its so thick & stiff. The cunifer stuff is fantastic. Just like the factory dark brown stuff that is corrosion resistant and very bend-friendly.

I can't believe I missed the opportunity to buy a new tool - I must be getting sick.

Aston and KTL,
I don't mean to hijack this thread but I think that my dumb questions may be appropriate to some of us who know absolutely nothing about brake lines.
1. What is cunifer tubing? Is it better than SS? Why not use normal steel as originally used on the 911?
2. Is tubing rust a problem in the 911? I examined the main lines on both my crashed '86 and my '78 build and neither appear rusty on the outside or inside, and;
3. What is an ISO bubble flare? is that the standard flare used on the 911?
Thanks in advance.
Cheers,
Johan

no prob

1. Cunifer is easy to bend and form
2. I think porsche used a copper alloy
3. ISO bubble is the standard porsche flare, and other European mfgs

Yep copper nickel ferrous tubing. Excellent stuff similar to what Porsche has been using for many years.

Fedhill USA (fedhillusa.com) is a good resource for technical info. I get my tubing and tube nuts from Belmetric.com

I use Eastwood's copycat of the the fancy flaring tool that Fedhill offers.

brake line flaring tools

I believe this tool was originally designed by Sykes-Pickavant and is a FANFREAKINGTASTIC tool that makes perfect flares every time. If you make a number of brake lines, the tool pays for itself very quickly in satisfaction & quality flares.

The split-bar wingnut type tools that are so cheap & prevalent are complete pieces of garbage that should be banned from the market. They make crappy flares (almost impossible to make a good flare with them) and typically weaken the tubing by putting tool marks right under the flare. They're downright dangerous IMO

Thank you guys for the valuable and helpful info. This board is the best!
