Thread: Braided brake lines. improve braking?

If you do buy hoses from os more likely then not wont have any ADR approval

I was caught out by that. Bought new +4" extended hoses from UK and mechanic wouldn't fit them because not ADR approved. Fair enough I say, it's his reputation on the line. The UK sourced hoses are now in the parts bin under the house.

It's more than just reputation, he's in court if he fitted them and something failed and there is an accident.

Although I think the chance of a good quality imported braided line failing and causing an issue, there are ADR approved braided lines available here. Mound these with 30 seconds of Googling, although the lengths and descriptions don't make a lot of sense.

ADR Approved Brake Lines

This site says that Goodridge stainless braided lines are ADR approved.

So, if you're that way inclined, there are some legal alternatives available.

I've got braided lines on my P38, no noticeable difference in brake feel, but they are damn strong! I caught a large tree branch on mine and dragged it along (unbeknown to me) for a few km of rough bush track, collecting all manner of bush debris along the way. The line did not break/leak/give whatsoever.

Better research that, I got goodridge hoses from the uk, now this may be state specific, but when getting the car engineered they had to either be adr, tuv, fmvss (goodridge has this), blah blah approved! I did a lot of research on this, will see if I can find where the info was.

Pirtek make them and are approved, and use good materials, they can also do std (better than OEM) approved rubber.

Challenge Accepted.

So instead of doing TAFE today I spent the day with a brake tester (just the pedal pressure unit) and a set of each new rubber and high quality teflon braided lines. Plus new fluid (all on load bar the fluid).

Fitted the new rubber first to the D2, and clamped off the rest as far up the rubber as possible. Also fitted a logging pressure monitor to the caliper bleed port. Ran a basic test of pedal pressure vs caliper pressure.

The braided hoses definitely transfer more pressure compared to even new rubber for the same pedal effort, therefore you achieve the same braking effort for less pedal effort.

Reran the test withthe gauge on the end of each hose as well and results were duplicated. Same with gauge straight onto pipe.

Challenge Completed.
