Ford Fusion owners have reported 5 problems related to brake master cylinder (under the service brakes category).
Its the abs. I have changed the brakes gotten new master cylinder and I still cannot get full brake control. Still pushing pedal almost to the floor. My mechanic checked on this site which showed others with same problem. Which he stated is a factory defect.

The contact owns a 2008 Ford Fusion. The contact stated that while driving 20 mph, the brakes failed. The contact was able to stop the vehicle. The vehicle was taken to an independent mechanic for diagnosis where it was stated that the master cylinder needed to be replaced. The vehicle was not repaired and the manufacturer was not notified. The approximate failure mileage was 28,000.
When backing out of a parking spot I depressed the brake pedal and it went straight to the floor. The car did not stop. I put car immediately into park and then pumped brakes. Pressure seemed to return to the brakes so I proceeded to back out again, testing brakes consistently. Brakes seemed to respond but seemed "soft" still. I drove car to mechanic without incident, thinking the problem was the master cylinder. Mechanic informed me that the problem was not the master cylinder but rather the abs hydraulic control module and that he had seen this same problem with four other Ford vehicles, two of them Fusions. Mechanic stated that when he looked up the symptoms I reported to him in his "identifix/oem" database that this problem came up associated with a technical service bulletin from Ford, including the instructions for how to repair the problem. He could not find a recall notice for this problem, however. This appears to be a manufacturer's defect and I am perplexed as to why there is no recall. I will be contacting the Ford motor company to investigate further. My mechanic repaired the problem which cost just over $2000 and did include him taking the car to a Ford dealer to reset the abs and associate the repair with my VIN. Two days since repair and I have not had any brake problems.

Was driving and as I went around a corner, the brake pedal (which was slightly depressed) went completely to the floor. Lost all pressure. I pulled into a parking lot. Turned car off and back on. Gradually pressure resumed. Drove another day or so and it happened again while I was going straight. I went to the dealer. Had my master cylinder, brakes, rotors, and brake booster all replaced. That was the beginning of September. Now in December, it is happening again.
The vehicle would randomly lose its breaking efficiency. The brake pedal would go all the way to the floor and would require 3 times more distance to stop. The vehicle was taken to a Ford service center for repairs. The correction completed included: test drive, found brake pedal is low due to air in the system, check for leaks, found master cylinder is leaking on the inside, replaced master cylinder, bleed brake system, perform abs system bleed and retest. Then again on 02/14/2012 the issue reappeared without warning. Took vehicle back to Ford service center and the following corrections were completed. Test drive, cannot duplicate customers concerns at this time. (service center advised me that they bleed the brake, but didn't list it out on the report. On 04/11/12 again had the same issue come expectantly. Took the vehicle to a Ford service center and the following corrections were made. Found brake pedal goes to the floor and car does not stop very well. Found abs valve is stuck open, r&r abs module, replace hcu, bleed brake system, perform abs system bleed, bleed brake system again and retest.
