1968 AMX brake line

AMXFSTBK390 wrote: The PO of my 68 AMX started a front disc brake system overhaul. I got it with new rotors installed, new master cylinder mounted, new brake pads, new hoses (driver side installed). It is missing the short 3/16" brake line that goes from the master cylinder to the front disc brake line fitting (3-way-tee) below the vacuum booster mounted on the fender well. What are the sizes of the brake line nuts. I'm thinking 3/8" nut at the tee, and 7/16" or 1/2" at the master cylinder? I have a tube flaring tool kit that makes single flares. Should this brake line be double flared?

Thank you for the warning. About 12 years ago, I got a bunch of tools from a shop that went out of business. This single flare tool is one of them. Evidently it was used for low pressure carb fuel lines?

A few minutes ago, I ordered the front disc brake line kit from American Parts Depot along with a new three-way-tee. The AMX sat two years with one front brake hose off, and the hard lines not connected at the new master cylinder. Fortunately the master cylinder still had the plastic plugs in it.

There is an article titled "How to Single Flare Brake Lines" at eHow. The sponsored link: NAPA Auto Repair. They give a warning to make sure the flare is of a uniform thickness. This eHow article should be deleted.

All I know is that everyone I've seen do brake lines and everywhere I've ever been doing brakes lines out of metal tube, it's always been the double flare.
NAPA article may be about that crazy metric or a bubble flare.
I don't know about you, but I'm not making my brake lines out of copper nor will they ever be single flare.
I've yet to see a race car's brakes done with single flare too.

I use the NAPA steel lines with the dark green coating. Seems very easy to work with and doesn't rust on a DD. I did ask about the EZ Bend and I think it only comes in large rolls. Would probably be a good investment though.

One of them is the "bible" on these cars from a British publisher. They use flared COPPER brake lines!!! In the United Kingdom a copper nickel alloy brake line is very popular. It is called cunifer. It does not work harden. Volvo, Aston Martin, Porsche, Audi use a copper/nickel alloy brake line. Here in the USA it is approved by the DOT. NAPA sells cunifer brake line and it is called EZ Bend. As with all brake line it is important to support it properly. I have owned six classic UK cars.
