Squealing brakes when cold ..every day!!

What kind of brake pads are on the car... Factory?... OEM replacement's??... That can be fixed!!... What has been done to the brakes to resolve this problem???

OMG! This is exactly what I'm having. I have a new Q60 from May 2015. Has this squeal problem in less than 4 months when the mileage is 2000 miles. Since then went back 4 times to fix the same problem. Infiniti Montclaire claimed that they changed new brakes and pad yesterdaym but this morning, the sharp noise came back again. Seeking for advice and suggestion, pls........

It's probaly missing the brake shims. My 2008 g37 type s didnthe same thing and I got new brake pads new rotors and calipers and brake lines. But when I put the car in reverse to back up a loud squeal would happen. Upon further inspection I noticed my pads had no shims. Once the shins were lunricated and put on problem was solved. I most likely guarantee it. If they put on the brake pads with no shims its going to make that loud squealing sound.
