Then look at the other pics. I don't know if that black stuff is paint or not, but the surfaces and even the cooling slots are much lighter in color. In addition, this black stuff is the same stuff that's one the edges of the bases.

I do agree with you, however, that cores are not required for "rebuilt" disc brake pads.

I can't explain it. All I can say is I have been changing brake pads & shoes now for almost 50 years and have never come across pads that look like this.

Wait a minute! I just noticed the brand name "Euro" on the box. Someone recently said on this very forum "if it's Euro brand, run for the hills" and I agree. I have had a little experience with "euro" rubber parts and I can tell you this brand is junk.
