If you have an old 2009-ish CX-9 with the Ford brake system and the brake pedal sinks...It's the ABS module.
3 master cylinders over the years and it was the ABS module. Replace with new and either have the new unit flashed with the calibration at a dealer or download the calibration to your scan tool, then re-upload to the new unit.
