The latest on Cages and Braided hose ??

[N1CERB]

Morning Folks,

Have there been any recent changes on the NZTA thoughts on braided lines fitted to cars please?

I have a Mk2 Mexico Escort that has been built from the ground up as a tarmac / track car but keeping everything road legal for the UK. BUt the car has a full Safety Devices roll cage (powder coated so no stickers) and braided lines for all fuel system, brakes and clutch.

When I was last over I was told there would be an issue with both of these and so I nver even looked at road registering. But this time round I want to put the cars on teh road so I can have some fun and not have to rely on trailers all over the place, plus not be able to do hill climbs etc, etc...

Now I had the hydraulic clutch fitted by Herbert's in Auckland and they also plumbed in my fuel pump and pre-filter set up. But none of these have any fancy tags on the hoses, so how do the testing people know the difference?

Perhaps I was not told the whole truth?

The cage is bolted into the car just now and I dont have any cert for this. Could I get around this in any way on a road registered car??

Any tips and advice much appreciated?

Thanks

Dave...

Welcome in

First off, you can use whatever you like for clutch hose, so long as it's fit for purpose.

As for brake lines, they USED to have to conform to the relevant FMVSS standard (FMVSS106) and be tagged and certified to do so. However, I note that the VIRM (the inspection bible) no longer lists any specific requirements for them and simply states:

REASONS FOR REJECTION:
17. A flexible hydraulic brake hose (including
connections):
a) is leaking brake fluid, or
b) is insecure, or
c) bulges under pressure, or
d) is twisted, stretched, chafed or
e) external sheathing is cracked to the extent that
the reinforcing cords are exposed, or
f ) has metal connections that are excessively
corroded, or
g) has an end fitting that is not attached to the hose
by means of swaging,

So as long as it's good quality, and not damaged, then you should be okay.

As for cages, that's a different story.

Road cars are only permitted to have "half cages", from the B-pillar back without a motorsport authority card (unless the cage is an OEM fitment).

To get your car allowed for road use it'll have ot be registered with MSNZ as a motorsport vehicle and used as such, you'll then get an authority card, which will exempt your cage for road use and allow you to get a WOF.

Of course that then means your cage will then need to meet MSNZ specs, and I'm not sure what the current legality is on bolt-on cages. Best speak to your local MSNZ or LVV certifier as anyone in here probably won't be qualified to give a definitive answer.

Excellent news on the braided lines, thats one huge headache out of the way for that one! The lines in question are all still brand new by th eway, not even any fluid running to the brakes so all good!

I take it there are no issues with braided fuel lines then? I assume this as Mark at Herberts used some when he made up the fule pump arrangement for me...



I like pictures, much easier than words.

Roll Cage - Last time I had to show certs for the cage and did not have these. Especially the Mk1 Escort as its proabbly 30 years old by now! My best bet woul dbe to remove that one and get one made or not bother at all as the car is way too valuble to race anyway. The Mk2 though has a brand new cage fitted and has welded brackets in places but bolted in others, there were issues four years ago so I assume they still exist?

I will check the Motorsport route as a good few of my Kiwi mates have ther licence and can possibly help more with some research on my behalf.

Still very pleased (dare I now say Stoked) at the braided hose rules!!

My braided brake hoses on the TVR passed inspection - they are not tagged or show any approval markings. I was told it was the style of braiding that was being checked - if they are crimped in a certain way (which good hoses tend to be) they will be fine.

That is good to know and a HUGE turn-around from when I went through the process.

It was like getting wisdom teeth removed . . .

Wow, that's nice.

Cheers fella, the rest of the car is much the same and there must be about 2k's of hose in there!! I have done many of the lines myself using JIC compression fittings, so hopefully these are sweet??

While not wanting to disappoint. My Elise had to have its braided brake lines replaced with tagged versions when I imported it in 2006. I'm hoping that the good news reported above is a change that has occurred since then!

It is

Great news for me. I did not even put my cars on the road last time because of this.

All brake/clutch lines on all the Atoms are braided hose. There are 7 cars that I know of in NZ. All are complied under LVVT.
