Unhappy 08 1k rear brake caliper grinding

So last night I finally got my bike rebuilt after it was stolen and wrecked. Bought and installed a new M/C and rear brake with new pads as well. Put brake fluid in and properly bled until no air remained in line. now I'm having an issue with the brake pads slightly grinding up against the rotor. I checked to make sure the axle is aligned properly on both sides and it is. I noticed that the piston inside the rear brake is not decompressing when the brakes aren't being applied. Surely that could be the issue...? Right? Rear brake caliper is new though so im not sure why that would be happening. I'm supposed to head out of town this evening and could use any advice on what to look for or check next.

Thank you,

You need to clean all the brake components on the rear. Id buy a rear caliper rebuild kit. They are cheap. Take the caliper apart including the pistons and thoroughly clean them. Install the new seals from the rebuild kit. It will work fine again.

is the disc new?
there could be a light rubbing sound when you wheel the bike until the disc & pads have bedded in.

Can you move the caliper by hand side to side?
