Ceramic Brake Grinding?

Do you know, or can find out, what brand of brake pads were installed back in Sept? I ask, because I’ve discovered that certain brands create conditions like this. It may be a mild brake chatter. Although they are not dangerous or very damaging, they are unsettled and undesired. I will never get brake pads again from Autozone after a similar brake feel like this on two separate cars I had years ago. Sticking to Raybestos, I’ve not had that problem since.
