hard brake line doesnt seem to seal/tighten

[notoptoy]

It is very easy to do (lose it), and when you do have the ferrule, it's just as hard to get it in there correctly, I had it, and it still leaked - necessitating the replacement.

Hi all - It's been a while since I've posted. Last year was a busy work year (so much for being semi-retired) and I hardly touched the car.

Anyway, I'm finally working on the car again and am determined to finish it up and get to Solvang this year!

So this is in regard to the 67.5 rear brake union - not knowing there was this little NLA ferrule inside the large female nut, I tried to puzzle it out on my own and this is what I ended up doing:

I put a bubble flare on the forward end of the short hard line that goes to the flex line over the rear axle, figuring that the standard inverted flare from the long chassis line would seal against the bubble flare. I had to really tighten the fitting down, but it did seal.

So I'm second guessing myself and questioning the wisdom of my method. I wish I had just not used the original fitting and put a standard 3/16 female to female union in instead.

I'm concerned about how safe my union may or may not be. Any thoughts?

Thanks in advance!

I also lost the little ferrule. I replaced both sides of the original line with standard flares and a union. While there may be no leaks, you will always have that in the back of your mind, at least if your mind works like mine!

Ferules and nuts are illegal for propane/natural gas, you have to use flares. So I would think you should feel safe with the flares.

i cannot seem to blow up the attachment , but it looks like that conection is a double flare type (no ferrule )

I just did my Dakota brake lines , sometimes the flare on the line goes crooked , or to far up the line
I had some I thought were tight but another 1/2 turn fixed are you sure the fittings are the same thread ?
it is a double flare ? right

I have a spare one of those goofy fittings complete with the ferrule...

[mikeb]

I have the fitting, but not the ferrule...

Now I'm really curious - could you post a picture?

Thanks!

I don't want to take it apart for fear of losing that little bit of unobtainium!

I agree, that is a flare fitting in that 2012 pic not a compression sleeve (ferule) type.

I can't remember if it was notop or spl310 that gave me a heads up on that little nugget. Mine fell out and rolled across the floor and I would have thrown it away had I not been told what it was!

I had one custom made after I lost mine as well. Welded two male ends together.

Thanks for all the previous info. I didn't think that joining those two brake lines without something would work. Found the ferrule fitting on the ground. Nothing seems to amaze me with this car. Going to attempt to reconnect tomorrow.

That little ferrule is worth 10 times it's weight in gold. Mine rolled away into a black hole and I had to change the lines to eliminate the need for it.

Like most, I did not reuse that brake line junction. Since neither the front nor the rear brakes are stock, I replaced all the lines, the brake line manifold in front, the fuel lines, and the clutch line. Once I discovered the copper/nickel line, the bending became much easier.



Not show quality but functional for several years now and mostly hidden by the engine.

Certainly sounds as if it should be included in the "What to remove/save before taking a roadster to a recycler."
