Hard braking or just slight pressure?

any pressure on the brake pedal at all and the sound goes away.

Maybe time to replace pads.

You better check those pads before you drive again. There are no "squealer bars" on the pads to warn you when they are close to the end. If you are already nearing or at the backing, the next sound you may hear is a horrible grinding followed by several "Ka-Ching$" for new rotors.

...and now for the funny part. It started last week so I replaced the pads today; sound is still there! :shrug:

Cross drilled rotors often crack at the holes. When you changed the pads did you take a good look at the rotors? Perhaps a pad is barely catching a crack edge :shrug:?

They looked ok but I wasn't looking for a crack; I'll have to pull the tires in the am and look again. Thanks for the suggestion.

Also check your set screws. I don't have set screws any more after having a similar sounding issue. When I removed them, they were bent a bit which made them rattle under braking.

Try putting a little grease on the pad backing where it makes contact with the piston and the caliper. White or molly grease work the best, but any grease will do. You should also check for play in your wheel bearings.

I use a stick (think glue stick from kindergarten) copper grease on my pad backings.

Greased the pads after checking everything else; drove around to check and the sound was gone. :nanner: Pads were greased yesterday, probably just not enough. Problem solved, thanks to everyone for their suggestions. :bow:
