I have a 2010 GMC 2500 with right over 57k miles. I changed out the rubber portions of my brake lines with braided stainless. While in the process of bleeding them, I snapped a bleeder on a caliper. While going to get parts, the reservoir gravity drained. I filled it up and tried auto bleeding with a scan tool, mighty vac and the old fashion way with the engine running and with it off with no results. I have put two and a half 32oz. bottles in checking that I don't have any air in the system. The pedal still goes to the floor very easy but takes 3-5 seconds to return!
