Braided Brake Line Failure

[gaz914]

I was speaking to a mate of mine at Oran Park last weekend and he mentioned he had fitted the Maltech (or Brake Quip) braided lines.

I told him that these lines are NOT suitable for motorsport use (and frankly I am not sure I would have them on my road car either).

As it happens, a line arrived in the mail today from one of our customers.

Fitted to the front of a race car - failed whilst at Eastern Creek.





The last pics shows clearly what happens to these.
The braided line is "held" into the fitting by a rubber sleeve.
The rubber sleeve fails and the braided line comes away from the fitting - generally when you are on the brakes hard!

We have several examples of this failure.

The Goodridge lines are made differently with a metal ferrule clamped directly onto the braided line.

The line at the bottom is the Goodridge one with the anti-whip collars.

Crikey, People will buy any sort of stuff if its cheap (we had a member on here want ing to buy SECOND HAND brake hoses !).
If youre right about that things construction then selling it is just criminal.
I stopped using braided lines when one started leaking on my bike. The braid stops you seeing when the rubber is perrished.

Dead set!
i had only ever heard that Braided Lines were the Ducks Guts!

Hence why they were so expensive and sort after...

Is it only that brand that are no good? because they are a cheaper brand?
Or are all Braided brake lines no good??

Braided lines improve pedal feel, so that is the advantage.

I'm not sure that the BrakeQuip ones are "cheaper", but definately not suitable for track use.

The Goodridge ones (bottom pic) don't have the issue due to the ferrule clamping directly to the braided line and the fitting.

The dodgy ones are not cheap! Gaz will be changing over all of my dodgy ones to proper ones once I get the car running again.

scary stuff !!

on my track car I've always made my own using speed pro bolt up ends and never had
one fail
in fact crimped braided lines weren't around or weren't common 10 years ago so all braided lines were made up this way - they arn't steet legal though
of cause for a track car it is handy to be able to make up what ever lenth or what ever ends
are needed and not have to wait for a special order

[mbrallying]

I make mine the same as you cheater and can vouch for them, never ever had a problem.

If they are known to fail, then how the heck can they legally be sold for use on a road car

Never thought of that point either T, hiding the condition of the rubber

[81GH]

was it front brake lines?
wasn't rubbing on the wheels.
cause i got braided lines for my car
and when was getting power steering fixed
when car was hoisted up could see full lock oneway
the line would scrape on the wheel.
i should fix that up soon lol

braided lines MUST be ADR approved for street use, as far as in know that has to be engineered or the Goodrich ones are the only ones ive heard of that are approved from factory
