I used Inline Tube for all of my brake lines (through Flea Bay).
I have 2016 GT brakes front (4 piston 14” rotors) and rear (13” rotors).

Ford has metric threads on the factory junction block on the rubber hose...same as GM.
Inline Tube also has the hard line fitting if you want to keep factory rubber hose.
I considered it, decided to do it once and be done with it.
If you look on their website, you can get hoses without adapters too.

BTW, none of local auto stores sell this adapter or even the correct hardline fitting.

Thanks for the info guys!  I went to O'reily's and Advanced and they had Metric or Standard but nothing that adapted both together.  So I think the hard line on my 69 Mustang  is a 3/8 thread and the 2014 rubber brake line is a 10mm.   You must be running 18" rims Nos681?  The 2014 Mustang Calipers barely clear with 1" spacers on my 17" rims on front.  I think there 13.2" rotors.    Thanks Steve

Inline has many different size adapters.
Do a search for GM, Jeep, Etc

Look at their online catalog and then search on EBay to see if they have a kit ready to go...usually cheaper than a single fitting.
I think 7/16” is common size too.

I wasn’t sure if I needed straight fittings or angled fittings.
That’s why I didn’t get a “non adapter “ hose setup incase i needed to change one end.

As Mustang Steve suggested before on rear line, tack weld adapter to frame bracket and you will only need one wrench to connect/disconnect flex hose.

Yes using 18” wheels.

13.2” barely clears 17”?
What model wheels (future reference for me)?

  Thanks!   There 17x8 2001 mustang gt wheels.  Im using 1" spacers for proper offset.  2014 GT rotors. I test fitted the spindles on to the rotors with the calipers.
 

The hoses i received all required 10mm x 1.5 inverted flare.

Everything at the stores and online were 10mm x 1.0 inverted flare or bubble flare

Only 10mm x 1.5 were banjo bolts.
My search was this past spring so maybe someone else might have made an adapter.

Might try SURR, Edelmann, or Dorman again.

On my Flea Bay purchases, both sales showed calipers, hoses, and tube nut with hardline cutoff cars.
I only received 3 and one was slightly buggered up.

I checked thread pitches with thread gauges from metric and SAE tap and die kits.

I went on a merry go round trip on this part of the project.

Thanks for wheel info too.
Appreciate it.

I had Granada spindles prior to 65 spindle install and Mustang Steve brackets for 2016 brakes.

I had hardline in front of spindles like Granada setup, didn’t like hose route.
Made new lines to connect in/near factory hardline location aft of spindle.

You dont think the above adapters will work with the 2014 lines?    I want to use the 2014 lines because they seem to fit around the caliper better.  They have a square banjo fitting mates up perfectly on the caliper. So I dont know if a after market line will fit in the tight area where the line attaches to the caliper. I have the Granada brakes now too. 
 

Even if brake calipers are different, no guarantee of course, the body hardline should have same size fittings on 2015-present.

I realized a moment ago ...2014.

I filled out my “ID ten T form” for today! 😂

Perhaps they are the same
Just different hoses per caliper setups.

Switching back to 65 spindles, changing brakes, rebuilding front suspension and steering all at same time.
I decided to make new lines and put some thought to how to approach it.

3/8-24 is still pretty common for brake lines.
I purchased a roll of Cu-Ni line and 3/8-24 fittings and flared away.

Im with MS on adapters. Just one more potential leak point.
Do it right with the proper fitting.

What oddball tube nut DOES NOT have a flared tube inside of it?

My lines from the  2014 Mustang are about 18" long so there is some room to work with.  I used adapters back in 2003 when I installed the Granada Brakes.  I used adapters for my 1995 Master Cylinder.  Ill most likely use them again...LOL   I hate to use the word cant but I really don't want to do any line flaring.  I tried it many years ago without any success.   Im ok with Adapters if they dont leak. 

Thanks BobE
