Due to where you live I would say that the rust issues are normal, and a brake pad separating from the backing is not normal, but not exactly rare either. Brakes are one place where you should not go cheap. As for the dealers response, I would unfortunately say they are right. Brake pads and rotors are a wearable item, and if the caliper has not malfunctioned, it is hard to hold Ford responsible for a defective brake pad. They are advising you to replace both rear rotors because they are sold in pairs, as are brake pads. As for replacing the fronts also, they may be trying to make some money off you, but without you taking the car to another dealer or an independent, it is hard to tel. I would doubt that the dealer would even let you take the car back without the repair due to liability. I hate to say it, but I would either pony up and pay for a full brake service or have them tow the car to your house. You can get a full PowerStop brake kit including slotted rotors and ceramic pads for the front and rear from Amazon for $400 with free shipping and the job can be completed in your garage with simple hand tools. Good luck
