Hello ! I have a front passenger side wheel that is squeaking , I checked the disk and pads h the today , the disk looks fine and is coming up a 10.5 mm (it’s min is 9.1mm) . Brake pad thickness was around 7mm . I did notice it dragging some dust as it was going round ? Also when I press the brakes the sound goes away , it’s a really annoying squeaking!! Any insight would be appreciated thank you

Check the caliper slides easily on its pins? Check the pads are not bar tight in the caliper bracket
The front brakes can bind a bit in my experience - especially on the early cars where the brakes were just a tad marginal (they were uprated later). Though often as not it's because the casting of the caliper bracket is a bit poor where the pads sit - a bit of judicious filing and wire-brushing to polish can help.
There is a slide pin which has been mentioned.
The slot at the lower end of the caliper casting (that the retaining pin passes through) swells with rust causing the caliper to bind on the retaining pin. This can cause drag and uneven pad wear. This is very often overlooked.
Some pads are more squeaky than others.
Some pads have plain metal backing plates, others have a rubber type isolator stuck on the backing plate, some people swear by anti squeal paste applied to back of pads.

Are the pads supposed to be touching the disk while I’m not pressing brakes ? Mine was tight on disk , I could move disk but it was a little tough
I can wire brush that ? Are you talking about the pin which you attach the little pin from brake pads set to ?
Yes the pin that has a retaining back up spring clip.
You can wire brush but if caliper slot very rusty it may need scraping out more firmly than wire brush can manage.
You can get new lower pins in a fitting kit
it's not so much bad as the fact that better stuff is now available
Same as there line you can only use BMW screenwash
