So I did the F body upgrade and everything went together just fine. I have no leaks and everything is put together correctly. calipers, rotors, pads, clips, crush washers. I used the F body bolts with the sleeves also.

The problem is that I have spent about 2 hours the first night and another 2 hours the second night bleeding the break lines (i know it shouldn't take that long) I used the 2 people and a clear hose and mason jar method and no more air bubbles, but the break is still a sponge! goes to the floor easy every time. They will stop the car pulling out of the driveway and moving slow but I don't want to take it out into traffic because it just doesn't feel right at all.

If I pump the break it stiffens up a little but after a few seconds its all spongy again. The OEM breaks worked fine and felt good and stiff.

This is my first time doing anything more then pads or rotors when it comes to breaks.

What am I missing here? Besides experience lol.
