MC reservoir caps

[bravohotel]

Hey guys,

I did my brakes this weekend, and when I went to bleed w/ my trusty Motiv Pressure bleeder, fluid came spraying out of one of the little black caps that cover the "low fluid" sensors. Probably at one time they were rubber, but now have turned into brittle plastic. I see no reference to them @ Fastlane, only the grommets. Anyone know of replacements?

Thanks
BH
