Rear brakes... smoking

I replaced the rear brakes on my lumina, and now they're burning... it seems like they're in constant contact with the rotor... too tight. Any ideas what I did wrong? It's on BOTH sides. I went pretty far... should I have pushed the pistons in a little further? I figured they'd set themselves to the correct position as long as I could get the pads over the rotors...

Any help would be greatly appreciated.

What year is it? Most of the Luminas with rear disc you must screw the piston back into the caliper, not just push it.

It's a 1993, but when I said 'pushed', I was just speaking generally. I did screw them in.

I had to mess with the actuator screw a little to be able to be able to rotate the pistons back in... is that what's causing the problem? Do I need to adjust the actuator?

I was kind of tires last night, You should always screw the pistons all the way in. They can't loosen themselves, only tighten.

sometimes the pads need filing to fit properly. if they set too tight or have burrs where they stamped the metal backing plate , they can stick. also you must bleed brakes . some think this is not neccessary but they have problems when their caliper pistons seize.
