Metallic squeal/scrape sound after doing wheel studs
 

*Moving this thread as it probably belongs in this section*

So I worked over the winter to replace the wheel studs as the PO had someone go ham on them with an impact gun. Taking them out was simple enough after I recognized the leverage necessary to get the caliper brackets off the front. Did the fronts, test drove and all was well. Finished up the rears a couple weeks ago and now all of a sudden I have a horrible metallic squeal/scraping sound coming from the rear.

Finally had time to take it apart tonight and seemed like the pads were sitting on the rotors so I flexed them a bit to the point where they were spread a bit, buttoned it all up and before I even left the garage, same awful noise. Ideas of what I fucked up?

Car is a '17 PP car that wasn't driven all winter, only has 21k on it and likely the original pads and rotors though both have plenty of meat left. Also car wasn't making this or any other noise prior to me taking on this little project. Thanks in advance.

Quick check now and I can see both rear pads sitting on the rotors, car is off, etc. Other observation I made was I couldn't recall seeing this bracket on the driver's rear before and seemed odd it wasn't connected to anything on one end, but seems it's just there to keep the brake line away from the wheel maybe?

Also what do I need to do to get the pads to sit back off the rotors again?

Is the "odd bracket" rubbing the inner lip of the rear wheel? It may have gotten bent.

That's what I was worried about but there's no scraping on the wheel and looking at it with the wheel mounted it's more than 2-3 inches from the inner edge of the tire.
