Brake assembly failure?

Moin. I recently took over a V70, in which the brakes (dishes/blocks) were made. Now I noticed a really bad metal sound twice, as if a sheet metal was grinding on the disc. This could only be fixed by a little backwards driving. If I look at the rear brakes like this, the thin mounting plates look different. To one have the up to 5 mm distance (HL1) or stop also, on the other hand, the end noses were bent only with one sheet (HR2). Question: Can it be that they move so mounted and then grind slightly on the disc? Brain
