Brake Master Cylinder problems of the 2008 Mercury Mariner

My vehicle had difficulty in stopping, needing the pedal to be pressed almost to the floor before it stopped. I changed the master cylinder in hopes that it would fix the problem but it didn't. The brakes periodically would work properly, but once again the problem would return. I stopped by the Ford dealership and they advised me that the 2008 Mercury milan was recalled for this defect, however, my 2008 Mariner wasn't on the list to be recalled. The dealership added that the parts for the repair was on back order. I still drive the car but cautious whenever I need to brake.

Re:NHTSA identifier 19v904 Ford internal reference number:19s54 although Mercury Mariners are not listed in this recall, my 2008 Mercury Mariner has the exact same issue, sticking abs valve. Ford will not recognize my vehicle as part of this recall. I have had 2 different certified mechanics work on the vehicle and both mechanics have installed new brake boosters, brake pads and master cylinders. The results from their work did not resolve the issue of soft brakes. The problem began when I made an abrupt stop while driving on a city street. The brakes were never fully functional after that. I believe the situation with my Mariner is identical to the issue identified in the NHTSA identifier 19v904. I also believe that Mercury Mariners should be included in this Ford recall.

Brakes suddenly stopped working while my 17 year old daughter was driving. A message appears �regen brakes disabled, check brake system�. Went to dealership and was told hcu and master cylinder needs to be replaced $4000 repair. Not acceptable seeing so many complaints of this issue that Ford has not yet issued a recall.

Car had 2,500 miles when both brake lights illuminated and only had manual braking. Car was towed to dealership where they needed to consult with Ford specialists to determine the problem because they weren't sure if it was the master cylinder or the brakes. The replacement part had to pulled from the assembly line because the parts were not due until 8-15-2007. Replaced master cylinder on 7-26-2007.
