Suggest that, where possible, a link to the Brembo product page is added, as it's a full technical specification!

Excellent thanks Gaz.

Andy I agree be good to get a library of Brembo technical drawings from the Brembo site but I am reluctant to link to pages as the link will inevitably die at some point. Will have a look later at downloading them.
