At 49K+ miles the steering wheel would vibrate when the brakes were applied. The local Ford dealer (Steve Coury Ford, Payson, Az.) replaced the rotors. Since then the brakes have been very mushy and when put in reverse the brakes make a loud squeal when light pressure is lightly applied to the brake pedal. The dealer addressed the recall on the brake booster on the second time back but I am now on my fourth return and the dealer doesn't seem to have any idea what to do. They have been in contact with Ford but to no avail as yet. Has anyone experienced a similar problem and if so what was done to correct the issue.
