I have a 51 3600. I redid my rear brakes, new everything. The fronts didn't look so bad so I just cleaned them. I'm trying to bleed the system using the 2 person pump and hold. I can't seem to get a firm pedal. I can pump all day and it just goes to the floor. With that said, I do get a little fluid and air when I open the bleeder value. I also don't see any fluid leaking from the system. I spent a couple of hours doing this and didn't seem to get anywhere. What am I doing wrong
