Mountain Bike Disc Brakes Squealing

mountain bike disc brakes squealing
Disc brake noise. How do I stop it?

I bought a mountain bike with shimano M485 Hydraulic disck brakes 6 months ago. The back brake has always made a loud squeal when I hit the brakes. I thought it would go away when they got broke in, but its still here. Now the front brake makes a slight squeal when I use it.

Any idea how to correct this?
