Hi myself and other members have nailed this one a few times, Pagid are eurocarparts own brand and carry neither E11 or E9 certification Brembo will as will Febi Blueprint EBC and Mintex, please read up on the net about E11/E9 that will explain all about the ratings and why, the best fluid is Comma ESP 4 as it is rated for all VAG/MERC/BMW anything cheaper will eat the seals over time, best stuff for lubricating slider pins is silicone grease and for the pad sliding surfaces on the callipers a thin smear of copper grease. Live Long and Prosper.
Steve.
