I have derbinator disc brakes on my truck. I am using 84 K20 rotors and calipers. What brakes lines do I need? The 84 K20 lines have a metal tube on the end of it. I tried looking up 75 K20, those were all rubber lines but they used a 7/16" banjo, my calipers use a 10mm banjo. Please help! I would prefer not to switch calipers. Thanks!
