Looking for advice on replacing all the hard brake lines

[zKars]

Forget to put the fitting on? No problem. Cut the tubing in the middle, slip the missing thing on, and then practice your low current TIG welding skills....  Use some 18 gauge copper wire strands for filler wire!

Got the package from Fedhill today, everything looks good, just a couple of strokes with some 0000 steel wool and you get a mirror finish on it.

240Z 1972, are the brake hose fittings double flare or DIN flare (mushroom)? I'm having some SS braided brake hoses made up and now I'm not so sure, sure looks like DIN to me.

I believe they are all double flair. I think that is the way I made mine, but hopefully someone can confirm that

[grannyknot]

That is what I have always thought too but my pics of the stock fittings sure look a lot more like DIN flares than double flares.

My notes say, 'double (not bubble)'.  A better point of reference, though, may be the chart (with photos) that appears on the FedHill website:

http://www.fedhillusa.com/webnuts/common flares6.pdf

Note in particular the picture with caption that reads, "10mm x 1.0 Asian nut with SAE/double Flare".

Now, compare that with the picture immediately below with the caption, "10mm  x 1.0 metric nut with DIN/ISO flare"

From these pictures, it looks like the best way to visually detect the difference between the two is to look at the flare from the side and check the contour of the back/bottom side of the flare (rather than the front/top side).  The back side of the DIN bubble flare is almost flat/square.  The back side of the SAE double flare is tapered (45 degree angle).

Fed hill is excellent! I rented their flailing machine. Super high quality and 100% perfect flairs every time.

I dumped the S lines 100%. Flex SS from the caliper direct to the hard line

Good refresher for me, too, because I had nothing in my notes to back up the 'double (not bubble)' comment and all the usual Z-car references (FSM, Wick Humble, etc) seem to overlook this point.

Good luck with the 'flailing machine' (sorry, Travel'n Man. I couldn't resist )
