The majority of brake discs these days are made in China, regardless of the name on them. I wouldn't be surprised if it wasn't the same for pads.
European legislation ECE R90 is there to ensure that the pads are as good as or better than the original equipment. Any new pads supplied in Britain must have E11 in a circle stamped on the back.
If I'm fitting new discs, I try to fit pads from the same manufacturer but, if I can't get a brand match I'm happy to fit any of the other known brands. Discs from Quinten Hazel, Mintex, Bendix, Comline, Juratek, Borg & Beck, Blue Print, Motaquip etc are all excellent brands and they all have matching pads.
