Guys,
Is it possible to 'warp' the brass brake line distribution block? I don't recall mishandling the one I'm using in my '65 Satellite restoration, but it's been an insurmountable source of leaks.... I can see it weeping into the papertowels I put around it. I've flared and reflare the tubes. I've torqued down on the nuts harder and harder...
I'm using InlineTube brake lines, and some of my own flared ends (I converted from 1 to 2 circuit and used the distrib block from a '67 Coronet).
The leak(s) at the block will drain down the front circuit MC reservoir (and soak all the rags I put against it) in about four days.
Thanks,
-Art

I'd grab another drum splitter & try it & that'd tell you if the problem is in the brass splitter block or the quality of the flares. That'd be much easier than doing any more reflaring which you've already tried

Aftermarket brake lines need a new distribution block or it will leak. Flares are different.
Wow! OK, seriously? If the flares are different at the main block, how about at the rear axle splitter and all 4 brake cylinders... ?
But if you're right, Inline Tube will get one H of a @#^%$#  call from me tomorrow. I've talked to them about the problem already - they mentioned nothing like this... their lines are supposed to be OEM spec.
Thanks,

I replaced lines in a 67 barracuda and used all the original blocks, including using stainless ... no leaks

First I ever heard of this. You might be thinking AN fittings which are 37 degrees. For the original poster, are your brake lines stainless steel? If so, they can be very tough to seal. Original material here is better to use. It is possible the distribution block could have a crack in the housing.

are any of inline tubes flares leaking at the block ?
steel or stainless lines ?
with stainless lines I have had luck with a SMALL
dab of anti-seize to the threads of the fitting only and cycling the fitting 3 or 4 times at the connection to get it to seat fully - anti-seize lubes the fitting
Just helped a friend with a 61 Vette - he bought all repro stainless lines and EVERY connection leaked - got them all to seal with the above method
Never had a issue with OEM block - repro blocks yes
I would also verify 1 of the inner seat's on the block isn't damaged
It also will help on SS lines to slide the nut back and put antiseize on the tube where the nuts touches it .

Yes lot's of lube/anti seize and use a good quality line wrench to tighten and loosen and re tighten. And also make sure the seat has not fallen out of the block and of course that it is clean inside. Good luck with it.

Thanks guys,
I'll try all your tricks with anti-seize. The tubes are all OEM steel. Some are my own fabrication. The leaks are in both Inline Tube product and my own.
I did a bunch more tweaking last night. And this morning there were no puddles under the car - so far so good.
Just one of the tubes at the block is still wet though - and when I apply brake pressure it weeps.
I haven't used anti-seize, but I'll give anything a try. I plan on buying a new brass block from YearOne.
What's frustrating is I've done brake line replacements like this several times on old Mopars I've owned, spanning over 25 years, and never ever had this level of leakage before - and if there was an occasional leak it would take 10 minutes to re-flare, re-seat, re-tighten and it would be fixed.
I'm feeling cursed, or suspecting really poor steel material in the tubes - as if the tube is hairline-cracking in the flare. But I can't see any flaws.
Argh. Back to the garage I go.
Thanks again,

 ....usually the problem for most doing their own brake systems is, they aren't using the right wrenches, buy a QUALITY tube/line wrench, using "regular" wrenches only eggs the flare fitting causing the base to fish mouth on the tube flare, which results in a leak, and no matter how tight you keep tightening it, it still leaks, after this the line/flare and fittings are junk....
