Screaming brakes.
Left rear sounds bad when I drive, can you adjust?
Very annoying. 
The brake pads are replaced, but it sounded bad before too.
Thank you for advice.

Yeah and when you reassemble  lightly sand the glaze off the pads and make sure the slides work freely and pads are setting flat. The one with the divot goes toward the piston and if you used EBCs it is a bit ling and needs taken down a hair to set flat.

Thanks again for the tip Wheels and NMK.
