EPDM is the type of material (ethylene propylene diene monomer) and is in common use for many applications. The 70 is probably the inside diameter of the o-ring in mm. I have no idea what the SH specificies but do know that o-rings go by material, inside diameter, and thickness. I GOOGLED "epdm 70sh" and found lots of references to it in parts lists for all kinds of things, including expresso machines, mostly from manufacturers in eastern Europe. You may be able to find this part from an American distributor of some of these manufacturers. You may also want to try the Evektor Aircraft (SLSA) importer. They may have them in stock and could be cheaper. I think this brake system is used on several of the eastern European manufacturered LSA, so if Evektor America http://www.evektoramerica.com/ does not stock them you might want to try some of the others listed at http://sportpilot.org/learn/slsa/ For future reference here are standard o-ring size charts metric o-ring sizes: http://www.lutzsales.com/metric_o-ring_sizes.pdf American Standard o-ring sizes: http://www.lutzsales.com/standard_o-ring_sizes.pdf Please keep us posted on what you learn as we may all need this information in time.
