I believe I already introduced myself and posted many years ago when I joined.

For various reasons, my 06 Jetta with 153k miles here in Florida got no use for a few months last year. When I went to drive it, the brakes would not fully release when the pedal was released. I changed the brake fluid, including the clutch and it worked well again. It then again sat outside unused for a couple more months and now the slow release brake pedal and sticking brakes problem is back. I jacked up the front of the car and tested the front wheels by applying the brakes to see if they would stick. They did not. I then repeated the test for the back wheels with the same curious lack of sticking. The pedal stll returns very slow. All the rotors and pads are fairly new. I am greatly puzzled. I have not yet checked the one way valve to the booster, but that is the next thing on my list.

I do still need to change a noisy front right wheel bearing. Could a funky wheel bearing actually be the cause of the drag, even though it doesn't pull when dragging?

Any suggestions are welcome.

Have you checked your vacuum system for leaks?

The flexable rubber brake lines have collapsed on the inside. Same thing happened to our 2006 Jetta TDI DSG here in Central Florida. Mike

I finally got the time, changed the hoses and bled the brakes. It is quite

a bit better, but the pedal is still coming up slow, and the brakes stick a bit for a few moments. I have attached a photo of the driver side of the brake booster, as it looks like there is corrosion. Could this be a reason? Am I OK with simply spraying some WD40 in there to loosten it up?
