rotors "humming" after pad replacement, help!

[tmmed789]

I just replaced the rear brake pads on my 2005 mazda 3 and now they are humming on the rotors at 15-40 MPH, not when I am applying the brakes, just while driving. Noise goes away when I brake. Never had this problem. Rotors are fine, alignment is fine, I put everything back together again. Anyone had this problem or know what it is from?

You may just have to seat your pads properly. If you do a google search, you will find a procedure to seat your brake pads. Give that a shot and see if it helps.
