Braided lines

[Colapop]

I reckon you should check with VTNZ or summat (Motu maybe??). The word I got was that screw on type ones will not pass WOF. They must be crimped at the banjo...?

[imdying]

Okay so there are no screw in type ones that do comply?

I've just had a look at them and the following is stamped on the lines
DOT B.H. SAE J 1401 01/06 3MM. H.L

That hose is compliant with New Zealand laws, and you should be able to get a warrant.

It may just be that the actual hose itself is of that standard, not the entire hose. Regardless, that SAE J1401 is the number you need.

In theory, a hose that can be disassembled and reassembled can't be certified in NZ. Out of curiosity, do your hoses have marker paint across the join of the nut and banjo?

[SuperDave]

No marker paint. Why what does this mean or would it mean if it did have?

Also would you please explain why disconnecting the hose at the nut connecting to the banjo is bad? I would have though that provided you clean off the old loctite properly and use fresh loctite when you tighten it up again it would be just as safe as it was to start?

The marker paint would imply that it was certified assembled, and you can see if the paint has been broken, (i.e. disassembled).

You can't disassemble and reassemble them because the olive used on the connector needs replacing if you're to do that. The loctite isn't the issue.

Sounds like the same brake line I purchased a while back for my last bike - the little o-ring seal that fits at the screw together join can be purchased for about $4 each from your line supplier if you unscrew them (why though?). Paint a line on the nut/join yourself for piece of mind so you will notice if anything moves over time.

, and the braided stainless steel hosing also helps the cooling of the fluid too. To what effect for the latter, probably not much.

not much at all.
The fluid in a bike's brake system doesn't actually move much, so the only part that gets heated is down near and in the caliper.
On top of that, the inner lining of braided lines is teflon or nylon;both poor heat conductors.
The braid is more for mechanical protection

[Pixie]

Apart from the fact that the water content of the fluid boils,these repeated heating and coolings,and other compounds it finds in the fluid - the water content turns acidic.Another way to say it is...it turns into an electrolite,and turns your brake system into a battery,removing metal from here,and depositing it there.This is how you get corrosion pits in master and wheel cyls.

I test brake fluid with a multimetre - positive to earth and neg into the resivour....anything over 300 millivolts means the fluid has absorbed too much water.The same thing happens to your coolant,it turns into an electrolite...anything over 600 millivolts and dump it.

Anyone mentioned yet that when braided line fail they FAIL. Thats it no brakes at all. The teflon cracks after a while. They don't have the multi layered lining rubber lines do.

I've got screw in ones fitted to the 550F and they pass have passed WOFs at all the testing stations I've taken it to. The braided line has a plastic sheath with the approriated markings. The bango fittings have these stamped on them also.

Just noticed that my bike has braided lines, they are crimped style but I cannot find any stamps on them?

Dont know how old they are???? Will they kill me?
