Did you ever get this sorted out? I have the same problem. I've tried replacing the vacuum pump valve that many discuss but it didn't help in my case.

I have the same issue. I noticed it started happening around the same time the temperatures began dropping, although that’s probably just a coincidence. The good news is that it doesn’t appear to be negatively impacting the performance of the brakes. That said, I’d still like to figure out what’s causing this.

Did you also try replacing the vacuum check valve? If so, how is the master cylinder and your brake booster condition?

Thanks for the suggestion. I didn’t think to look at the vacuum check valve as the sound was coming from the brake pedal arm in the footwell. I’ll check that, as well as the master cylinder and booster. Though, my car only has 45K km so I would hope these components are still in good shape.

True, the check valve in particular fails easily, the rest mentioned rarely fails.
