A friend (female) had her front brakes done and they only replaced the pads. The brakes pulsed thereafter. I took it back for her, left the car, and they called me later that day saying there was nothing wrong. I went back the next day and road in the car with a mechanic. Miraculously the problem reoccurred. left the car again and they called later saying the rotors needed to be turned but there was not enough left, so needed new rotors. Cost? $170. I did it the next weekend myself for $70 with same rotors from Autozone. Buyer Beware!
