Hello! Just a quick question here. I have a 2016 Subaru Forester 2.5i. Does anyone know if Subaru OEM metal brake lines are steel or another metal/alloy? I noticed a small 6 inch spot of brake fluid under the vehicle this morning just past the drivers side wheel well. While I haven't pulled panels yet it would appear to be coming from the metal line itself due to the location. If they are steel on the car I was thinking about upgrading to stainless or another non rusting alloy. Does anyone know? Any help would be appreciated as even the dealership can't answer the question.
