Hmmmm so DOT 4 has a better/higher boiling point , something to think about, I have all new rubber lines, all new wheel cylinder in the rear, new disk up front, maybe 7 to ten feet of old line running to the rear.
Yeah... not sure about the eating rubber thing... I read a lot before deciding. I did like the lack of moisture creation specifically for vehicles that sit a lot... I'll keep an eye on the lines to see if there's any impact. Thanks @Icetech
