The one thing that makes me think that the calipers are sticking is the constant dragging sound I hear when I drive at low speeds. Then as I speed up it turns to a hissing like squeel. There is no pulling whatsoever but from what I could see through the wheels, I think I saw a discoloration to the rotors possibly indicating overheating. Last I drove it, there was no vibration on stopping so the rotors are not warped. This morning when I told my wife I was driving the 300D instead of the 230, she asked why and I told her I needed to check the brakes before driving it again. All she did was sigh but I have a feeling when I get home tonight, I guess I can expect to hear some more nagging.
