My 03 GM started pulsating during stops after driving for about 400 miles a day. Pulled the rotors and replaced them, took all of 20 minutes for each side. Strangley everything looked ok but when I went on the road and went to stop.. SMOOTH as silk again. Not bad for 32K. Went after market with Bendix pads and premium rotors.. I expext to be doing the same thing in another 30k....
