Squeaking brakes

Hello everyone, I have a topic now that I’ve been getting on my nerves since we’ve had our big ones: the brakes squeak. Sometimes more and less. But when they start, usually when it’s wet or wet, it gets louder and worse with every braking. When we bought the car (Bj. 11.03), the brakes have been re-made before (discs and coverings). Meanwhile, without success, three different workshops have tried on the brakes. In the meantime, it says that we must live with it. Frankly, I don’t think that is acceptable. Not only with a Phaeton, but in general. I feel that squeaky braking is a considerable deficiency and it can’t be that you have to accept something like that! Does someone have an idea or a suggestion, which I am still trying to do? hmen, or who can I contact at VW? Many thanks in advance and many greetings Martin
