Need a Brake Master Cyl fitting Identified... pic

[Bennett]

I have a new pre 69 master from a fj55 that I am using for a clutch slave on a V8 conversion.
Using the brake master with the larger bore than the slave gives me more throw
for my conversion. Mark whatley set me up with this idea and I have been satisfied for 2 years now using it.
My problem is my brake master started leaking so I purchase this oem pre 69 master and the end fitting is different.

My old 55 master used a compression setup which was fine for the clutch but not what I wanted. I now want to go double flare with the proper fitting for the new master as seen in the pic.
Can someone give me the correct size of this fitting and where I might find one?

thanks

Early was a 9mm, somewhere around 1968-69 it went to 10mm. Hard to find fittings but I'm sure somewhere like SOR can find you some fittings. Brake line is easy to flare.

Well it must be 10 mm on the new one ... right?

Here is the old MC end cap and you can see the smaller diameter for the fitting. The older was also not a flare as you can see there is no seat in there for the flare.

So 9MM or 10MM...or.... ?

Kinda looks like the old one was a bubble flare, and the new one is a single??? If you have a auto droid store nearby you could take it and see if the european (metric) hoses fit. I think they are 10mm.

Could you just unscrew and clean up the old "end" and put it on your new master??

Sorry buddy, no idea on the fitting size. I know evco didn't used to do rigid lines, but it might be worth giving them a call. I've got a flaring tool along with a hard line bender if you need it. Bret's question about using the old fitting is worth looking into. Call me .

there was a post on here that you can buy a 9 to 10 mm adapter and just screw in the old line .i have had them on several old 40s ive owned.or you can cut the line and reflare a new fitting available almost everywhere and screw it right in .try search maybey that will find the post even had the no at napa i think good luck
