You did not mention replacing the pad sensors; if you didn't replace them, it's time to do the job over again.
On the front brakes, you must have an MB Star Diagnostic tool (or similar) to disable the SBC braking system before replacing the front pads or rotors. Serious injury can occur by working on brakes with the SBC active.
