Query: Opposite of quiet

Installed these on my VW camper when I installed new rotors because they were the only ones I could find locally, and the brakes started making a really loud scraping sound. Thought there was something caught in between the rotor and pads. I finally ordered some different pads (last ATE pads for this vehicle available on amazon). There is not anymore loud scraping sound from the brakes.Thermo Quiet are also not very good at stopping the vehicle; they have about half the stopping power of the brakes I am used to.
