[E-Type] Hydraulic Brake Fittings

Hello All -

Call it beginners luck but I have been have initial success
forming bubble flares on Cunifer lines as I fabricate remote
bleeders during the rebuild of my irs. I have purchased a
stainless flex line to connect to the 3-way on the irs cage.

Here’s my question: It looks to me like the stainless flex
line fitting is a male ‘‘bubble’’ type fitting but the
original 3-way looks like it needs to receive a double
flare. Can anyone confirm this and if so what’s the best
resolution? Is there an adaptor of some kind (i.e. bubble
female to double flare male) or do I find a new 3-way to mount?

Thanks again for the help!–

Craig, On my SII’‘E’’ IRS the 3 way connector was clearly
double flare ( df ), and all the lines to it were also df
including the flex line from the car body to to the IRS. I
think you should consider getting a compatible flex line
rather than considering adapters ( which I have never seen !
). In a general sense I have never caught on to the usage
pattern of Jaguar re double bubble ( db ) and df…other
than to notice that no line ever had a db at each end …only
one. I have always use steel lines, and I gave up on making
the bubble myself. I always used long commercial db lines
which I the cut to length and put a df at the other end. The
db might be easier to make using the CuNi alloy tubing, and
i wish I had considered this option somewhat more carefully.–

Craig, John,

I’ve also had luck making doubles flares with CuNi pipe even
with a cheap flare-making kit. However, my luck ran out on my
latest job ( replacing the clutch master & slave cylinders on
my '61 FHC) when I tried to use the standard metal pipe.

All of the existing connections were double flares. There is a
good writeup on flares and a pretty complete range of
hydraulic fittings and Cuni pipe at http://www.fedhillusa.com

I was able to make excellent double flares after doing some
research for a better tool than the typical yoke-style cheap
kit. I didn’t want to spend $$ and found this tool, which
makes really good flares:

CAL164 CalVan Tools 164 SAE In-line Flaring Tool Set
I bought mine from http://www.denlorstools.com It cost
$32.13 + s/h.

BTW, I completed the job, bled the system but had a leak at
the master cylinder out line. No matter how tight I made the
fitting - even after making several new pieces of pieces with
excellent flares. I have concluded that the new master
cylinder is defective ( bought from one of the ‘‘biggies’’).
I have now got an original Jag part on order from another
vendor. I’m $75 out ( too late to send it back ), but what
really p*sses me off is all the work I have to do again. What
the *&%! is wrong with parts these days!!!

Cheers

Cunifer pipe is the only way to go. Much easier to work with than the steel or
SS lines. JMHO

Thanks all for the replies. Good info that there is never a
bubble on both ends. I take it that since the caliper
receives a bubble then the original 3-way fitting on the irs
cage must be a double flare. Since my source for the flex
line (one of the usuals) has the 3-ways in stock with bubble
ports it looks like the easiest course is to order that fitting.

Keeping my fingers crossed for a positive result on the
pressure test.

Thanks again!–
