Brake Disc Pads problems of the 2006 Ford F-350

The vehicle shook at 65 mph and shimmied when the brakes were applied. We first had tire rotated and balanced and a front end alignment with the replacement of right side ball joints. It did not correct the problem. When we returned the vehicle to the dealer for further repair, the dealer took us back to look at the rear brakes. The backing plates had failed due to rust and the pins for the parking brake shoes had pulled through. The dealer replaced both rotors, both brake shoes, the backing plates and the pads for the disk brakes.
