Electronic Brake Distribution (EBD)
WARNING: This page is about a different car, the 2006 Mercury Grand Marquis and 2006 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
The electronic brake distribution (EBD) controls rear brake pressure and acts as an electronic proportioning valve. It is controlled by the ABS module. EBD remains functional if there are 1 or 2 wheel speed sensor faults. When EBD is disabled, the red brake warning indicator illuminates.
