Pagid are not Eurocarparts own brand they are one of the largest manufacturers of brake parts in Europe and they are OEM for many major car manufacturers. I'm sure they do have some sort of deal going with Eurocarparts but don't make the mistake of thinking they are some sort of pattern cheapo gear.
I have no idea who makes Eicher brake components but even the staff in Eurocarparts don't recommend them. For the small difference in price I am happy to use Pagid, although for performance cars I would look elsewhere, Brembo, EBC etc.
