Emailed the manufacturer, this was the reply,
Apologies for the discolouration of your brake line.
When the hose is made it is pressure tested using water. It appears in these unusual cases the water has got trapped between the braid and PVC cover.
The braid is stainless steel, but there are many different grades of stainless. Most grades of stainless contain small amounts of Iron and Nickel. The small amount of Iron content can cause your line to discolour, essentially it’s rust that could be wiped off if you were to remove the outer coating. Although, this might be unsightly, it’s perfectly safe.
We will cover this defect with your warranty*and send you a replacement.
24 hours later a replacement arrived, no mention of wanting the old one back.
Now to fit it.
