NO Brakes

While traveling at 65 mph my 2001 Taurus brakes failed without any warning. The brake fluid level was fine, no leaks and just four months before this occured I had warranty service inspection at Ford who said everything checked out fine. Repairs cost nearly $1,500 on both front & rear brakes to replace both master cylinders, warped drums, pads, etc. were needed. (I did have front brake pads installed 6 months earlier.) My warranty miles are still valid at 58,700 though the 6 year deadline has now passed. Ford did all warranty service since I purchased it. I could have been killed. Shouldn’t this problem have been previously discovered? HOW COULD THIS HAPPEN WITHOUT ANY WARNING? I believe Ford should take some responsibility for my huge towing & repair bill. DO YOU THINK THEY SHOULD BE CONTACTED RE: THIS OCCURANCE AND POSSIBLE ACTION?
