I have a 2002 Kia Spectra. We have replaced the rotors 3 times, but prior to doing that we were having problems with our back brakes. The mechanic we were going to said nothing was wrong with the back brakes, but to just keep driving the car. We kept experiencing problems with the back brakes and decided to take it to another mechanic. He found the back shoes were worn thin, the drums needed to be replaced as well as the wheel cylinders.
Once all that was taken care of, the car started to shimmy again when applying the brakes. Took it back to the mechanic who replaced the back brake work thinking they may need adjusted, but it wasn't that. The rotors were warped he said. So we went back to the first mechanic who did the front brake job. He replaced the rotors. A week later the problem came back. We had them checked again by the mechanic who did the back brake job thinking once again it could be the back brakes. He said no, it's the front rotors again. He checked the calipers and they are not sticking. He checked the brakes hoses and says no leaks or problems there. Master cylinder is OK.
Got a third opinion today: rotors warped! This guy today says unmatched rotors and cheap brake pads. So the mechanic I figure has been putting on cheap parts. They are over heating and causing the rotors to warp. Does this sound logical or far fetched? Help!!!!
