Rattling Brakes after a front Rotor and Brake Pad change? (I'm skeer'd)

My Rotors were warped, (175,000 miles and like a bucking Bronco in a Hard Stop) so I went with some slotted and drilled rotors as I have an ungodly 1.5 hour commute each day and wanted some cooling. (I know dirt and chit will build up but my boy has his own truck now and traffic is more my norm). I changed both sides of course and now I have an annoying rattle that goes away when I apply some Brake Pedal, worried that it's wearing the pins, the Calipers not Hot, so not worried about a lock up at this point. I changed the "M" springs and am thinking about putting one on the bottom. Any ideas?

 

FYI, I went and got OEM Anti Rattle Springs and then put the aftermarket on on the bottom and the rattle is gone.
