My car has 11,000 miles on it and had the front pads and rotors replaced due to excessive shaking through the steering wheel. Now after I wash the car I have excessive brake dust after a day or two on the wheels. Before the dust was minimal after a week or so. My service manager says the pads are standard Cobra pads and factory rotors, plus my pads squeal a lot now too, any idea on why or what kind of pads should be on there?
