Anyone ever had brake drag after changing rotors and pads???

I finally saved up for new rotors and pads, but now the brakes are dragging when the wheels are jacked up. You can't feel it while driving, but when I jack up the front tires, there is definitely brake drag. The kind where the wheel stops the instant you let go after spinning it.

Anyone ever had this problem? They are Summit extreme performance drilled rotors and Hawk Performance pads. Oh, and it's a 72 C-20.

Thanks for any input in advance.
