    I sure hope you figure it out... I just did the same exact thing as you. In fact, I have the same rig practically. I installed my 14bff rear disc setup, bled the hell out of the calipers (non caddy) and I have no pedal. The "brake" light is on too. I am gonna try a new prop valve as my next step.

    You still have air in the system. I had to unbolt the calipers off the brackets, drop them down and hold them on the rotor and bleed them to get all the air out. Its a little messy but it worked. Do you have the calipers on the right sides. More than once I have seen where people will put them on the wrong side and the bleeders will be on the bottom, Stizkid there is a proceedure to reset the proportioner valve after bleeding the brakes so it gets re centered. after your done all four wheels you go back to the rear brakes and do this proceedure, turn the ignition on. Brake light should be on. Open a bleeder screw as a helper applies the brakes hard. Close the bleeder before the helper releases the pedal. Re apply the brakes hard and the light should go out. It may take a couple of tries to get it to go out. if not go to the front and try the same thing. This should re-center the valve. If not you will need a new one
