Hi guys,

I can't find the adapter I need, to be able to plug my front disc brake line to a summit line lock a friend gave me.
What I understood (I may be wrong) :I assume I need a "7/16 female inverted flare" to fit my singe flared brake line on one side and a 1/8 NPT on the other.

I think the diameter I need is 7/16 as the front line I have is a disc one and the nuts are bigger at the front than the rear drum lines.

Could you advise the type of adapter I need, and maybe sell two of them to me if you have some? (ordering on summit website is $60 minimum shipping cost for france).

Many thanks,

Nico
 
You will probably find the solution I came up with a bit unorthodox but, hey I'm kind of known for that. :D

The line lock I have came with all kinds of adapters and crap that I just wasn't willing to stack up to make something work.

The threaded line holes in the lock are 1/8 NPT and the threads on the 1/8 steel compression fittings (mandatory for brake lines) are the same thread pitch but not NPT.
I took the nut off of one end of the compression union, used thread sealer and screwed the end of the compression union right into the lock on both ports (in and out)

Then a quick cut of the front brake line and put the two ends in the two compression union ends with the ferals and nuts like you would normally do with a compression union.

The lock is mounted on one of the master cylinder studs, and it's as clean an install of a line lock as I have ever seen done before.

Didn't even have to bleed the brakes because I filled the lock with fluid after the bottom line was on and then installed the top line.
The brakes never felt any different after it was installed, and it's so close to the master cylinder it probably would have cycled out any air bubbles on it's own anyway.

In the US in order to run line locks on the street it has to activate the brakelights or it's illegal to use.

If you decide you want brakelights when the lock is on, contact me before you go cutting into anything to add a switch.
I can save you a lot of time, expense and hassles, as I have a completely new way of doing it without having to add a pressure switch.

That's kindof what I did too, except I reflared the lines.

Worked great, and not even so much as a damp spot in about a year so far.
:D Using the steel compression unions dodged the flaring bullet.

Is it that tough to flare a brake line?

Not at all as long as you have a good flaring tool and the line doesn't split from doing it.
But why bother is the way I saw it, since steel compression unions are totally acceptable and legal for brake lines.
