01 silverado 1500 rear calipers sticking

[allaboutchevelles]

I just replaced my rear brake pads today and now both the calipers seem to be sticking a little. When I drive the truck around the block and get back home the wheels are real hot and you can smell the pads burning. but when I back up on a hill and put it in nuetral it will roll down the hill so they dont seem to be sticking real bad. I even put wd-40 under the piston boot and worked the piston in and out a few time, didnt help. This seems to be a problem on these trucks. I guess I need to replace both calipers???? anyone have and suggestions??
