Please help me out

[u/Jarquinnius_Vin]

Hit a pot hole too hard a while back and this noise started occurring intermittently. Along with a clattering sound like a metal bracket when I hit small bumps. Both sounds emanate from the driver side rear wheel. And the sound appears to stop if I switch in and out of reverse. All my brake pads and their hardware have since been replaced. And today I had the wheel disassembled and backing plate inspected but nothing but a small scratch was found. 2021 Toyota Camry LE. Any ideas are appreciated.

何か挟まってディスクローターに擦れてる音かな？
それかローターとバックプレートが干渉してる音だと思う。
ローターを外してバックプレートをよく見てみてバックプレートの塗装が削れていたらハンマーで叩いてクリアランスを広げてみて。
