Having to remove the caliper pistons due to one of the nipples shearing and lots of swarf falling into the caliper when I drilled it out - so far one of the piston seals has torn and only two of the pistons are out.

What rubber seals should I be using? From a quick search the number is coming up as 20 4872 51, but the seals which are in the caliper at the moment are 20 4872 46 which is a bit strange, as they seem to be for a Porsche caliper..

Any ideas? Surely is the 46's are in there already I could probably just get some of them.. http://www.ebay.co.uk/itm/Genuine-40...3D111038604934
