I've been noticing lately that my brakes squeak when I first drive my P5 in the mornings. The noise goes away once the car has gone about a 1/2 mile or so. Is this common, or should I have the dealer look into it. Braking power is otherwise normal, and the car only has about 1600 miles on it.

 

It might be due to colder nights, condensation forming thin layer of rust whcih gets scraped off when you start driving it.
I notice that rotors turn rusty right after I wash car!
