cobra owner with f150 ???

Any of you guys have a 99 f150 4x4? My truck that my wife inherited, when I got my cobra(she cant drive a 5 speed, and is afraid of the power) is having a brake issue. I just replaced mine in the cobra with brembo oe rotors, and hawk hps pads, but I have gotten out of touch with the truck crowd. The brakes seem to drag when light pressure is applied to them, resulting in a semi truck, braking sound. any help is greatly appreciated, thanks chris

rears are maybe a year old, new rotors, and best pads(supposedly) that the shop had, they still look good, rotors are smooth, and atleast 1/4+" pad left, fronts had ceramic pads, middle priced, put on a month ago. and the rotors aren't older than 3 years. Thanks, chris

mainly when you drive through a parking lot, or are moving up with traffic waiting for a light to change. I can make them do it in those instances. If you hold the brakes lightly and just let the engine pull with out pushing the gas.
