Custom brake hoses - Which threads?
Hi,
I'm planning to use the Euroquip custom braided brake hose system as found in the Rally Design catalogue on page 35 of the 2003 catalogue.
Firstly does anyone have any experience of this system and do you know if it is SVA compliant. I am aware that there was a thread a little while back
which said something about there having to be a central pipe over which the braided hose would push and then be clamped in place by the screw on body.
Do you know if these hoses meet that criteria?
Secondly, does anyone know what the various fittings (threads and seat angles) are on the Sierra master cylinder, sierra rear calipers and Cortina
front calipers so that I can order up the correct fittings. Think Automotive have just about every type of thread adapter you could think of so it
shouldn't be a problem to convert anything which needs converting. I also need to know which fittings the Fiat Uno compensator valve
requires.
Finally, what is the best budget flaring tool I can buy? The one from Screwfix or the one from Machine Mart or a.n. other?
Thanks guys,
Craig.

The best i can do is tell you ford threads are M10,and the clarke flaring tool kit from machine mart did the job for me.
Plenty of practice with the flaring tool makes perfect,a little dab of grease on the flaring die makes it all come out nice i found.

Thanks Bob, I might just nip into Machine Mart during the week and pick one up.
Anyone else able to comment on the braided hose question?
Cheers,
Craig.

The flares on the ends of your solid pipes will be the bit you will need to know, single or double. The brake pipe fittings are all M10 male or
female. I looked at the ones I was removing and copied them, can't remember them all though but the ones where you use a female to join to the
flexy is double and the ones into a recess with a male union are singles usually. You will need some nuts to secure your flexy into its bracket.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Peteff,
Can I assume that these threads are Metric FINE and not just standard metric?
Any ideas on the Cortina calipers (M16) or the Fiat Uno compensator anyone?
I appreciate the bit about double and single flares and it should be obvious which to use I hope.

The uno compensator is M10 which is why i prefered it to the mini type which is imperial,as far as i remember the only double flares on my car are the
front flexy's where they pass through the bodywork.But this all depends on how you plan and fit your pipes,if you do a search on single and
double flares you should throw up some pics and drawings which will explain and helped me a lot.

All the brake stuff is M10 Fine IIRC.
If you can possibly borrow a decent tool then do so. I've got one of the screw in types and it's not that great without a lot of practice.
Then a mate lent me the big Sykes-Pickavant jobbie and it's brilliant. Case of clamp pipe, pull lever, job done!

Hornet,
That's a very kind offer which I may just take you up on thanks! I'm not quite ready for copper pipes yet, I just need to get my flexible
hoses sorted out so that I can position suitable mounting brackets and then I plan to strip down the entire chassis to scrub it and paint it
(Yippee!!)
I'll give you a shout nearer the time I need the flaring tool if that's okay.
Thanks again,
Craig.
ps. James, thanks for the advice, I know what you mean, I have used both cheap and professional tools and I know which I prefer too...

Braided Brake Hoses
Craig, I've used Euroquip for various projects. One thing to be aware of is that because they are a re-useable fitting there is always a small
chance of the fitting becoming loose. Great if you are racing and keep an eye on them. If not, I'd recommend crimped goodridge hoses made to
order. Ask for Ian at CAM auto (UK biggest supplier)
http://www.camauto.com/miniprod11.html
(They don't just do mini)

Hi,
Thanks for the warning.
Is there no way of locking the fittings? It's a bit scary to think that they could come loose...
Cheers,
Craig.

Braided Brake Hoses
You could always use just a spot of Loctite thread lock on the nut threads.
With Euroquip the nut traps the braid onto the ferrule which then crimps the olive onto the PTFE inner.
I would not get too over excited about them working loose - It's just if you want to fit and forget as they say I'd go to Goodridge. Last
set I bought (4 hoses between 12-16 inches with special bulkhead fittings and banjo's at calliper end were about a tenner each from CAM, you
save very little with euroquip at say 3.50 a metre and then the fitting 2/3 quid each)

it might be worth remembering that (iirc)there's some issues SVA-wise with modular/rebuildable brake flexis

Hi,
Thanks for the warning about SVA issues with these type of fittings but I think the Euroquip ones are okay as they have the central tube onto which
the PTFE hose slides. SVA were unhappy with hoses where there was no inner tube on the fitting which doesn't surprise me in the slightest as I
would expect the security of such a fitting to be quite poor.
I'm not too sure what to do now to be honest but I think I might still just get the euroquip stuff, bearing in mind the potential issues, as it
will allow me to keep moving forward and I can make up the hoses as I need them.
Cheers,
Craig.
