6000 miles
When i brake very slightly at around 30 mph, i can hear a whistle sound, and when i brake harder is not here anymore. It looks like of the sound when your pads are worn out. But i don't think it's that, my other car (TLs) I had never change pad or disk and i sold them around 60 000 miles.
Could it be a bad ajustment, or nothing to worry about. May be just due to the conpound of brake pad.
What you think ?

 

Probably just some slight pad noise. Do a couple hard 60-0 stops and it should go away. Or just wait it out and it may go away on its own. Or just take it to the dealer and have them deal with it. Of course, the noise probably won't occur while its there!
