WHY AM I HEARING THIS SOUND WHILE DRIVING?

2000 Lexus ES 300 • 12,800 miles

Hi. I just changed my rear break pads.I did not rotate the caliper pistons clock wise while compressing them.I have a slight scraping sound now. Can I start over and rotate the pistons properly? Break dust shield isnt touching rotors and I dont know what else would be causing this metal on metal sound. Thank you

If you shoe-horned the new pads in, there's no need to turn the pistons. Did you have the rotors machined? There is likely a ring of rust buildup and the new linings are a fuzz offset compared to the old ones and they're riding on that rust. That will wear off in short order.
