Feeling distraught, trying to change my back breaks and I have really been struggling with this caliper slide pin bolt. At first I thought the bolt was stuck in the threads and rounded it but now it seems like it’s spinning in the threads smoothly but is stuck in the bracket. Been shoving some permatex penetrating but doesn’t seem to be helping. I’m 22 and about to give up and get it to a mechanic, would really appreciate some advice!

2011 Nissan Altima, I have a video where you can see the bracket and bolt move as one while the actual caliper stays still.
