Braided brake lines

[Motu]

I don't think Alex was talking about them lasting the life of the vehicle,just the component.

But that's just what it is - the life expectancy of a Japanese vehicle is 7 yrs,that's why you will find almost all Jap Imports are 7 yrs old.So the vehicle was expected to last 7 years and the component manufacturers made sure their products would last beyond that,no more is required - in Japan all brake,steering and suspension components would need to be replaced at that time,along with seatbelts and any other safety related system.We are playing catch up with vehicles well beyond their expected life span,that's why new regs keep coming out.Like seatbelts are snapping in accidents - asked why and the manufacturers say they need to be replaced at 7 yrs,so we have to find some phony reason to get them out of our pool of cars.

Alex is involved in compliance,I just see inservice - 10 yr old brake hoses are perished and cracked,7 yr old hoses are fine.We also check for bulges etc,but it's only a visual check - I have seen plenty of burst hoses,not one had external deterioration,we can't see the inside.

Oh,and PT - old Aussie and British/Euro hoses are physicaly perfect externaly even at 20yrs,quality? dunno,but if I see nothing is wrong...nothing is wrong.

hey guys I asked the expert --this is the guy the auckland testing stations ask when they aren't sure if something is up to WOF standard on a motorbike.
Keep in mind his is the OFFICIAL line
You guys are missing the point--It isn't a matter of quality of product its PROVEN quality of product.
WKKD --if you have brake lines with a certification of compliance -be it a bit of paper or markings on the lines.-then they comply -plain and simple.
Posh--Personally I am not prepared to take the risk of a brake line failing because some idiot didn't assemble them properly.
Quick question -What kind of brake lines do most combat aircraft use? Yep braided lines
Are they replaced after a limited number of hours use--YES
Why? -no not a flight of fancy -The lines are tested through a number of duty cycles till they fail
Then they build in a pretty big safety factor and tell the end user that the lines need to be replaced after that period.
Rubber hoses have isssues -we all know that-but they do have one good feature. You can flex em a heck of a lot more times than you can a bit of woven wire

Point 3: You can flex them sharply more times than woven wire. Brake lines shouldnt have sharp kinks in them anyway. Wire will last longer if it isnt forced into sharp bends.
Point 2:The reason things and people are cerified is legal liability. You can get idiots anywhere. I will rely on certification if that is all I have to go on. If I know a little about the issue I will keepit in mind but not limit myself to certified providers. There are people out there who take far more care over their work than some of the high volume certified engineers.
Point 1:Proven quality is different to acceptance of legal liability. They are close but not the same. Accepting legal liability often means proven quality, but not all proven quality products accept legal liability

True,Golemand are having to redo their hoses,same hoses,just the new ones have a number stamped on them.The quality is the same.

Mate we will have to agree to dissagree on this one.
Actually now I was mulling this over last night and I wonder.
The isssues with braided lines are indeed perception.
if its a case of what the eye doesnt see.....
Why dont we slide an outer casing of rubber hose over the braided line ?.
Your average testing officer aint gonna see the difference .

Err thats spelt mutliple is spelt as Multiple, usnfae is spelt unsafe.
just trying to help

Thanx, Mr QsauiEliv.
And thanx for not taunting me becoz I suffer from keyborad dyslixijadio ... dyoiuoa... dxyliax... dicklessai... D Y S L E X I A. (There. Dunnit.)

And BTW - if you look back at my lastest post - I had to replace my quality Aerotek lines with some that to my expert untrained eye looked eggszachary the same (in fact, not as pretty), except they had the accepted markings on the sides of the hoses. And they were twice the price.

Another by the by - it's worth fitting (approved) braided lines, especially to replace the crappy flexy OEM ones on the VTR1000. No, they won't help you to stop faster, but they do feel a heap better, especially if you brake with one or two fingers most of the time.

so has any one any updates on this????? also what are the brands we can buy here in n.z that will pass , so where to go to get em?

Go read the VIR manual on the LTSA site. It explains what is acceptable for WOFs and what isn't. Basically, anything that is crimped is fine.

I'm new to "Kiwi Biker" (as of right now) and I've just fitted Aerotek-BSR braided stainless steel brake lines to my VTR.

Welcome to the site.

the front brakes on my rg250 are terrible and barely work until the lever is at the bar, i have bled and bled and there is no air in there or getting in and the pressure doesnt really pump up so im thinking i need a new master cylinder? is there any way i can open it up and fix it without a rebuil kit?

oh and the relevance to this thread is.... I just passed a wof yesterday, in fact a re-vinning exam, at VTNZ, and it flew through.

Something of that age should be given a complete overhaul... brakes are more than an eclectic collection of items, they're a complete system and must be treated and maintained as such.
