20. Here we have the finished install. All nuts are tight and the cotter pins are installed. I didn't have any problem here with my brake flex lines because I have the needed adjustment at the banjo fitting on the caliper, but if you are running the stock Volare brake hose, you will need to gently persuade the metal tube part where it comes off the caliper to move to the inside a bit. If not, the hose will rub on the upper ball joint nut and cotter pin.
