Hi there

I have a new brake Union form my 1968 FJ40 but the old pipe fittings are shot, can anyone tell me what I should be looking for (in the UK)please
 
9mm hard to duplicate
 
Thanks Mace, found these in the uk they say they are 9mm 1.25 do you think they will be right?

I think so, but others will chime in for the rest of the story..
 
Pretty sure the factory piece is 1.0 not 1.25...


Threads look very different between your two pics.
 
So, I replaced the 9mm fittings/lines on my 1965-45 pickup with the newer, standard, 10mm x 1.0 fittings when I upgraded the brakes to a dual circuit system

Just measured the thread pitch on the 9mm fitting and it is 1.0, not 1.25.
 
another trap to watch out for is that the replacement fittings are long enough to fit into the union I've had replacement nuts that are too short and don't seat on the pipe flare when fully screwed in

Have you found the 9mm nuts?
 
Have you found the 9mm nuts?

no everything on my trucks are 10mm and a few non metric bits for the PBR remote boosters that I think are 3/8 UNF or something like that I cant remember its been a few years since I did any brake work on them but I do remember getting nuts that weren't deep enough for the unions
 
You might ask if anybody on the forum with a pre-'70 cruiser did a recent brake change over and see if you can re-use their old 9mm fittings.
Offer to send a S.A.S.E. and they might give ya for free...
 
I have no idea if this is what will work, but it may be worth investigating:

Wow! That looks like it! That piece has eluded me for decades! I will have to order some and see how they fit. Thanks!
 
Ordered. We'll see.
 
I have no recollection of this. Sorry.
