Air Brake Related Problems of the 2007 Ford Edge

Air Brake problem

My wife and I both drive Ford Edge crossover SUV's. Both cars have major problems with the brake system. When you are driving slowly & got to put on the brakes, the brakes make a terrible loud grabbing noise & the car kind of skips to a stop. I have done some research on the internet and found out that many people have the same issue, but Ford refuses to do a recall. The Ford service rep. At the dealership I go to is trying to tell me that this is how the brakes are supposed to be. There is a major problem with these cars and something has to be done. We had another Ford Edge that was destroyed in a rear end collision & it also had the same brake problem. Three for three is not a good thing. The rear end collision was not a result of the brake problem.
