Fortunately at low speed, power brakes did not respond as normal and it appeared like power assist or even most braking capability failed. Driver was lucky to stop safely. "Check Brake System" displayed on the dashboard.
It appears as if the FEH brake assembly BM6Z-2455-A is discontinued or not available. Does anyone know if the solenoid can be purchased separately? Is Ford essentially not supporting any brake failures of this nature? It also costs $1033!!! Any help appreciated.

Further added notes: The brake feel simulator cut-off solenoid valve and brake pedal feel simulator cut-off pressure sensor don't appear to available separately. Could be a wiring fault or problem with the ABS module. Regardless, all expensive repairs. If the assembly or parts discontinued, Ford might be saying "Good Bye See You Later" to supporting important, complex component failures.

 

The picture above is incorrect. The hybrid system is a lot different. The consumer parts database at Giant and others can be incomplete, missing information, wrong and even correct. The hybrid brake pedal system is a very complex part compared with the ICE system. There are multiple parts and sensors and a large bracket which are not available separately so the entire assembly must be replaced or used parts scavenged from other compatible hybrids. I found this write up which is quite good....: Tech Feature: Ford Hybrid Braking (brakeandfrontend.com)

 

If anyone has a detail picture of the 2009-12 hybrid brake pedal assembly and/or basic technical service information, please post the picture or link. Thank you.

 

Followup - the Brake Pedal Feel Solenoid was replaced by a good used part. It has been working fine for over 3 months now. The actual brake system was fine all along but the bad Feel Solenoid was not able to replicate the feel of a normal hydraulic braking system so the driver thought the brakes had failed. Note that on the FEH like other hybrids, the brake pedal system is designed to make it feel like a hydraulic system when in reality, most of the braking is regenerative. So the failed part could be called a fake hydraulic brake pedal feel replicator instead. The part was from a one year newer vehicle so we might be able to get a few more years out of the old Hippo. Have a great day!
