where i can find O-ring for YA F-16 brake system YA not sale this

If you know the size im sure a regular O-ring from an automotive store would work, you might even find one online like McMaster Carr. If you have one good one left, gently pry it off with a blunt tool or and o-ring pick and see what you can get locally, I will check with Shaun Evans, aka Yellowaircraft and see what he says, He may be able to get one for you. Ill check in on this for you. Shoot me an email in a few days, John [email protected]

Thanks

Ive got a call in to Shaun just waiting to hear back from him, in the mean time I will look at my brakes and see whats what.
