Have picked up some used brembo discs for my ST3 with very little wear however they have blobs of some glue / resin on the back of each button which seems to prevent them spinning? I thought they were supposed to spin freely ? Should I remove the resin or just ignore?
I recently bought a brand new set of fully floating Brembos - they had the blobs of araldite like resin on the back of the bobbins. I think they are meant to help prevent the circlips from loosening.
