When you're done,pull the syringe apart,wipe it down really good,and store it in a ziploc bag away from sun light.My syringes last me five or six years before they start to swell and have problems going back together.

Copy that. Withe a little overflow around master cylinder then cap it, a little mess but sounds fullproof. Check that, how high do you fill the master cylinder, is there a mark on the inside?
