Diafragma

Even the tiniest rupture may allow your hydraulics to become aerated, with the resulting spongy brake's scenario. Replacing this item as a matter of course during your brake service or overhaul is just good, safe practice. A bit like wearing other protective items made of rubber which turn out to be useless if they have even the tiniest pin prick!
