Noticed a couple of things and wanted to know if they were common. It only has 30k miles and the pads look pretty new, when coming to a slow stop I get a squeal sometimes or a deeper sounding noise. Common with the Brembo's? Also if I start the car with the AC on and put it in gear I get a chatter from somewhere in the engine bay until I get a little bit down the road. Never heard anything like it before. Any insight is appreciated!
