In march of this year we had the sixth visit to the kia dealer in reference to brakes pulsating while comming to a stop at about40 mph in the past the resurface the rotors and adjust he breakes at one time they replace the rotors still have the same problem if feels like the caliper are stuck and make a rubbing sound and the calipers start to worp and to vibrate more and more , the dealer accuse my wife of heavy foot she travels 15 miles to work every day with not much stopping , we are just about to go back to the dealer to have them look at the problem the last time we went they replace the brake shoes . we dont know what to do.
