Dear all,

 

just got a lovely big box from minispares, including a set of front braided hoses. (Goodridge).

 

 

anyway, on the site, they state these are 'handed';

Firstly, the two hoses are identical. both ends are exactly the same thread length as each other & the hoses themselves are identical in length and in overall appearance.

 

Can anyone shed some light on this.? Has there been an error in shipping/packing by minispares.? Should the 'handed' aspect of these be obvious to the naked eye.?

 

 

And, as mine is LHD, should their instruction be reversed.?

 

Cheers as always

the thread inside the subframe mount is different depth. one side is longer for the pressure valve/banjo connection. (normally drivers side).

I think this one starts off with a class in History first!

 

In original production, for cars with single circuit brakes, they fitted a thicker nut (probably about 1/2 - 5/18" Thk) on the LH Hose of RHD Cars and this I'd say was the 'standard' nut. On the opposite side, they fitted a nut about 1/2 that thickness as the 'standard' nut wouldn't allow for the Banjo Fitting that is fitted on to of the RH Hose to seat (with it's copper washer) on to the top of the Hose for sealing.

 

These days, unless an original restoration, I use the thinner nut on both sides (and it's the same one on the clutch hose).

 

Now, what you really want to know - how to fit them on your car. As it's a diagonal spilt system, there isn't a Banjo fitting that is fitted to either Hose on the front, the pipe work is fitted directly with Tube Nuts, so, it won't matter.

 

However as a matter of assembly routine (precaution / checking) before fitting up, trial fit the Pipes to the Hoses and be sure that the Tube Nut doesn't 'bottom out' before tightening up on the Tube itself. No need to use spanners here for this check, just finger tight.

 

Oh,,,, Photobucket is off for maintenance, so sorry, no photos for now.

Cheers for the reply;

 

 

so then.? why state that the hoses are 'handed' as they actually are not. They are identical.

 

When replacing 'like-for-like', its not an issue.

 

hopefully I'm not missing anything here.?

Cheers for your continued support/advice Mokespider.

 

 

As you know, I'm replacing the brake lines (like-for like) as well as the master cylinder, front & rear hoses, front cylinders, and shoes all round!!

 

Keeping it 'as-is', rather than updating. Managed to get a GMC167!!

 

 

Thanks for the tip: Will obviously ensure the nuts don't bottom out before a tight seal is achieved.

 

 

As for the history lesson, 40 years on, PFTE/teflon tape is widely used nowadays for numerous applications. Is there any benefit/harm in a few turns of tape whist fitting all of this.?

 

 

cheers as always

Like I said the drivers side has a deeper thread for the banjo.

If you have a diagonal split system you might have issues as the hole is deeper on one on them.

As it says on their web site

I wouldn't recommend using PTFE or any kind of sealing tape or products on Brake Pipes, they don't seal on the threads, the flared ball that's put in to the Pipe should seat (in this case) in the bottom of the flexy hose and seal on that flare, metal to metal.  Other 'joints' like the Hose in to the wheel cylinder, seal with a copper washer.

 

Ah, photobucket is back,,,,

 

 

This is a pic of a hose that hose it's drill made too deep and the tube nut has bottomed out on the hex before it can clamp the flare on the tube in the drilling of the hose;-

 

 

There must always be a small gap, about 2 - 4 mm, between the hex of the nut and what ever it's being screwed in to.

I've got  a pair here that are also identical. Though all that matters is that the unions don't run out of thread before the pipe flares are seated. I can't see ptfe doing much as the seal is made on the pipe flare.

Not only does Spider type faster, he has piccies!

So then, the hoses should be different as stated BUT for some reason, sets are being dispatched that have identical hoses.

 

Do I contact minispares and ask for the correct 2nd hose, or will it be OK on a diagonal split system.?

It's the inner thread that's longer, iirc.

[b_sdaddy]

ok, I'm confused:

 

it's like a school test:

 

which sentence(s) is/are correct.?

 

 

 

A:   The hoses themselves ARE actually identical - they are not 'handed'.

 

B:   The female threads into which the hoses fit are of different lengths.

 

C:   The actual hoses ARE different, ie. 'Handed' and the length of threads are different.

 

D:   The female threads into which the hoses fit are of the same length.

 

 

I fully understand that an incorrect thread length could result in either; the nut 'bottoming out' before the flare obtains correct purchase, or the flare not working as the male thread is not long enough.

 

 

 

 

my hoses have thread lengths of 12mm (flaring end) and 16mm.

 

 

cheers for any clarification.

 

As I'm in Belgium, getting pieces from minispares is not an overnight process, and having to re-order a new hose is a week lost.

They'll be fine.

Faith restored MokeSpider, thanks and sleep well.

Wish I had known this last month when I was fitting mine. It was driving me nuts trying to work out why they wouldn't seal. I eventually got it that they were handed.

6 turns of thread internally and 15 externally on both.  Just make sure your pipe fittings turn a little bit less before they nip up - or there's a thread or two still visible like Spider says way up  up there ^^^^

 

One nut is thicker, but only by about 5thou.
