'02 Accord EX rear brake replacement

I had the rotors resurfaced and used ceramic pads but I wasn't sure how to
properly adjust the caliper pistons. I loosened the bleed valve and
compressed the piston as far as it would go then I screwed the piston in
until the cliper would fit over the new pads. Everything seems ok. When I
first put everything back together one wheel was harder to turn than the
other but after driving it around the block, including backing up a few
times, both wheels turned the same.

Does anyone have anything to add? Did I do it right?

When I moved the car out of the garage I found an adjustment screw on the
floor. It is a flat-head scew about 2.5" long with a threaded stud that
rides the screw to make adjustments. I don't know where it came from. I
looked on both rear calipers but didn't see anything like it or where it
could have come from. Any ideas would be greatly appreciated.

Thanks, Steven

 

Got a pic? Doesn't sound like a brake part.
