need some brake unions asap with IVA aproaching, where from
was readiing a post the other day on here regarding IVA tester spotting brake fluid and deeming the car unfit to drive!
i have noticed fluid slightly leaking from the bottom of the filler hose from resevoir to master cylinder.
where can i buy the following parts?
2x 7/16" male unions with proper hosetails and cup washers built in? all the ones ive seen (cbs etc)are 7/16" female
or 2 x 7/16" straight male to male union and 2x 7/16" female filler union as on cbs
and some iva marked 7-8mm id filler hose. cheers

Did you fit a copper washer (or alternatively Dowty seal) between union and the cylinder ?

It was supplied in the kit and was a 7/16 brake pipe union with a short flared length of copper pipe attatched. It's leaking where the filler
hose is clamped to the short copper section of pipe. Not ideal really.

Just get a local garage to put a flare on the copper pipe where it joins the hose or even a large blob of solder smoothed off with emery. This will
give a better fit inside the hose. Might need to anneal the copper end flare that goes in the cylinder as it will be work hardened and won't
make a good seal second time around unless you do.
Rally design do brake fittings.Rally design as do VWP.
Another possible is to use a copper/cunifer pipe for the whole run without any hose. pipe

Try some PTFE (Fluid or tape) maybe?

What sort of clip have you used on the hose? It needs to be a "fuel pipe" type clip and not a jubilee. Jubilees are a bit D shaped where
the screw is as they tighten up and leak on small diameter pipes. Even with fuel pipe ones they're best to be as tight/small a fit as possible
before being done up. As said getting a flare on the pipe end will help.

I would have got my arse kicked from here to kingdom come if I was caught using Teflon tape anywhere near hydraulics when I worked in the heavy
earthmoving gear, same with the marine engineering.
PTFE tape is for domestic plumbers, and as a last resort at that. The Loctite pipe sealant is a completely different matter.
Do the job properly first time!
Cheers,
Nev.

Nev is correct that PTFE would not be correct in this instance, however it is perfectly acceptable when used on the correct type of connection
(tapered threads) in the vast majority of hydraulic applications despite what some guy down the pub told Nev 30 years ago

Try Europa car spares , Or Think Automotive , they also do the correct type of hose complete with nspec sheet for IVA. As said use fuel pipe clips not
Jubilee clips

You wouldn't be so smug if you had seen the damage that I've seen caused by teflon tape. I've seen it sucked out of unions, and
subsequently wrapped in pumps and valves, causing all manner of expensive problems. Spent a good few years in the big mines working on the biggest of
earthmoving gear, and maybe an hour or so in the pub.  Fixing the poor design work of the yanks who built the stuff.
Teflon tape is for domestic plumbers, and no-one else.
Cheers,

I'm not smug in any way I just don't agree with your sweeping statement and feel qualified to challenge it.
Spent the last 11 years working on HydraRig equipment, american made, full of NPT fittings sealed with PTFE. Not yet seen a failure attributable to
PTFE tape.
I guess we all have different experiences sometimes.

I am also not a great fan of PTFE tape.
I much prefer loctite sealants (used correctly), although some people go mad and plaster the stuff everywhere when it's really not needed and
can clog up small oil ways and pipes just like PTFE tape.
I do use PTFE tape on mild steel BSP pipe work with cooling water in at work for quickness and the fact that the joints rust up and self seal if they
weep a bit at first.
I feel it's more of a personal preference situation.
