Im redoing the components in my braking system and will have a fresh start. New Master Cylinder, Calipers on the front, cylinders on the rear drums and new lines. I was about to buy DOT 3 and fill er up but Im reading that DOT 5.1 is compatible with DOT 3 and is better. Anyone done this already? Or should I just stick with DOT 3?
