This is the little o ring that goes between caliper halves. We *know* this is correct for all Brembo F08 and P108 calipers, it most likely fits ALL Brembo motorcycle calipers but we have not compared to any other application as of yet..... This is a proper o ring supplied by Brembo for this purpose.
This oring was used on all Brembo calipers including P08, F08, P108, 30/34, etc etc etc....
