M4 2018 only rear pads squeak very loud as you can see from the video even though i bed them.It never stops.

We smooth the edges of pads and the noise was gone for 30 minutes then it came back.Person from the service (not bmw) told me it makes the noise because it is made by textar which is cheap brand.I looked up on internet and it seems my pads are actually oem pads.So even if i buy new pads from my local bmw dealer they are also textar.What do you think can be the issue with rear pads?
