I have a 2014 edge sport awd. It started with a soft brake pedal. New pads and rotors were all installed last year, no issues. The brake fluid was full and there are no visible leaks. After multiple conversations it was determined that the master cylinder was the issue. I did a bench bleed on it, then a line bleed at the master cylinder after installation. Pedal was still soft. So I bled all 4 wheels. Pedal is still soft when the car is on. When it’s off the pedal will get hard but if a steady pressure is kept it will go to the floor. I removed the battery and air box and inspected the abs pump and the lines and everything is dry, with no codes. However. The only thing that stands out is when the pedal is pumped I can feel fluid going through one line more than the others. I jacked up the car and put it in gear. When I apply the brakes they all stop evenly, starting with the rear. Any recommendations would be appreciated
