I've been fighting this a while on a buddy's car. It is most likely the proportioning valve that repositioned while bleeding (air in system). I have one more trick up my sleeve before I throw in the towel.

Turn key on--don't crank. Make sure parking brake is off. Then unplug switch on mater cylinder on the proportioning valve cylinder (the white switch you traded out). Did brake light go out?
