Welp, the PO broke off one of the front caliper bleeders nearly clean with the casting and THEN, managed to break the tip of an EZ-out inside. Undrillable. Is that a word? Soaking in PBB now. Will degrease and attempt to TiG a nut to what's left of the bleeder and break it loose Anyway, in my search for the worst case scenario, a new caliper, found that the OEM manufacturer was Hella-Pagid? And then found this

Pagid 355792491 Caliper

ECS also lists it but they have no info on it whatsoever. Anyone have any experience with this caliper? Is it a bare casting? Does it come ready with seals/piston? Is it stamped BMW? Is it identical/different than OEM BMW? I can't seem to find ANY pics of it anywhere online nor does Hella/Pagid show any pics in their catalog. Rockauto does say that it fits all 330's as well as X3 and Z4. Tempted to order one just to find out.
