I bought a brand new 2008.5 Mazda 3 GT in September '08 and after 500km and a few weeks it is making some very strange noises when releasing the brakes.
When I come to a stop and apply the brakes there is no noise, the ride is completely smooth and quiet. However, as soon as I release the brake pedal and the car starts to move forward there is alot of metal on metal screeching/squeaking noise. It can be replicated every time and it sounds like the hull of a ship grinding against a concrete dock (its brutal). It can also be replicated going in reverse, when releasing the car from standstill. Again I must stress there is no noise whatsoever when applying the brakes regardless of speed.
I took the car to my Mazda dealership however the numbnuts there just told me its possible rust buildup on the brake rotors and it is normal. Apparently it can happen on cold days in the winter and the rust is removed when you apply the brake pedals. I can't seem to agree with that, because it does not happen when I brake, only when I release the brakes, as if the brake pads are still clamping on to the rotors, and the car is already moving forward.
Can someone please tell me if this is normal, or how to resolve it. And why are the rotors rusting on a brand new car after just a few months? I do live in Toronto, and it is quite cold here right now -0c to -20c on average, but this should still not be happening. Any additional advice or information is much appreciated as I am no grease monkey
