Ever since I bought my 07 Jetta the dealer told me they replaced the brakes and may hear some squeaking because water got in there. Well, it still happens. When I turn on my car after it's been sitting for awhile I can hear some high pitch break squeaking in the rear. After the car is driving around for a minute or so it will go away completely.
Anyone have an idea what is causing this? Brake fluid not pumping at the start quickly?

 

Do you park outside? Could just be the rust that forms when your outside.

 

brakes squeak no matter what, there are certain things that make it so you can hear it like if you get a lot of dirt on your rotors it will most likely squeak for you it sounds like once the car warms up it goes away so i dont think its anything to worry about
