Hello All,

A leak in my F-18 wheel brakes have been confirmed to be due to damaged o-ring. Brakes are Skymaster. The hub has one smaller size internal o-ring and another, larger one. I need replacements for the larger one.
Both of my main gears brakes o-rings are damaged (not sure how come both got damaged at the same time!)

Anybody know the diameter and thickness of the o-ring? I'm thinking must be metrics ones...

I will check with Skymaster-USA if they have some. Others?

Also, what is the axle diameter?. Got a small bend in mine and want to replace. Also think is metric...

Thanks
