alright i did the rear disk swap on my 14bff. used stocker 3/4ton calipers. it seems i cant get all the air out of the lines. ive got a super mushy pedal. its feelin like i have an infinite amount of air in the lines. every time i crack the bleeder i got air comin out. this is after big bottles(quarts?) of brake fluid. the front have bled no problem, all of my issues are at the rears. my gut is tellin me air is getting introduced somewhere, but wouldn't that mean there would be a leak somewhere? any ideas?
