I’d use them with confidence in Japanese/Korean or American cars(that don’t use ATE calipers). Akebono is an OEM supplier to all the Japanese OEMs, has a JV with HL Mando in Korea and Ford/GM/Mopar uses them. I’ve had the same knocking problem using many aftermarket pads on a Toyota.
I’d stick to Pagid, Textar, Jurid or Mintex on a European car. Wagner seems to be repacking Ferodo pads for their European applications. And now, Mercedes and Volvo are using Indian-made Dan-Block pads for service parts. Subaru and Honda are using ATE calipers now - I see NBK stamped on the pads. Else, I’ve seen Jurid/Pagid/Galfer stamped on ATE pads on BMWs and Fords.
