Took truck in for squeaky brakes for the second time and I am not happy with the outcome. First time I took it in they replaced only the front pads per the TSB. This time they tell me the rotors are glazed and should be turned or replaced at MY COST. they say the rotors are warped from heat. I have only towed a 2 place open snowmobile trailer last winter, other then that it is driven to work 10 miles round trip every day mostly city and highway, no gravel. Get your crap together GM! Miles were 15K when replaced front pads & 22K when I took it in this time.
