My ques. is after a 2500 mile trip pulling a 7500# RV there is a accumulation of rusty brown dusty residue on the front drivers side rim. I also felt a distinct pulling when coming to a complete stop while towing on this trip. It did it quite a bit but not all the time. Is it possible the caliper was sticking?Truck is a 98. 5 ClubCab 4x4,5 speed,3. 52 rear LSD,with only 22k miles. It's like new. I have until Oct. on 3yr. /36k warr. Is this a common prob. ?Any input is greatly appreciated. I going to my dealership Mon. to have my center console top replaced... yeah. . broken hinge.
