Hi i had trouble with a bleed screw snapping while bleeding. I also had trobble locating a replacement one as Seat would only sell me the full caliper for a daft price. Bleed screws are a weird size and think you would be hard pushed to find the right one at a motor factors.
I managed to get them from a ap supplier, Questmead ltd. Drop Steve a eMail hes the most helpful guy in the world

From what i can gather these calipers are based on the ap CP5200 series but have diffrent clips and pipes.
