2004 ford escape brakes pulsating?

Brakes pulsating on my 4wd 2004 ford escape xlt. We replaced both calipers and new brakes, rotors, discs and drums all the way around. Still pulsating. I'm at a loss. We have also drained fluid and put new in. Not sure what is causing this problem. At a loss of $$ or I would take it in to get diagnosed. Need help before I spend anymore on parts that aren't the problem. I hate this not safe to drive at all and the ABS light did kick on, but shut back off and hasn't been back on? Not sure what that's about.
