Replacement of rear brakes by dealer resulted in discover of parking brake problem and replacement. The parking brake unit is located behing the brake rotor and cannot be visibly checked during routine safety inspections. The brake components were corroded to the point of disintegration and the brake pads had separated from the unit. The vehicle is out of warranty by a few months and approx. 5000 miles. I rarely use the parking brake and the dealership stated that was part of the problem and probable cause of failure of the parts. Based on conversations with the dealership mechanic, and other auto mechanic acquaintances, this is apparently a common problem with this make vehicle. In an emergency the "emergency brake" would have failed and life and property would have been endangered. The explanation that non-use of a safety component can render it useless is not acceptable to me, especially since this part cannont be visually inspected during routine safety inspections. A complaint was filed with the Ford motor company and the response was simply that the warranty coverage expired and that no further action would be taken. Again, "unacceptable". . . The old parts were not returned and I assume disposed of. .
