if it's still silent and behaving, do a standard fork lowers service for now.Hurry up with your shock, would ya!

The bearing housing to damping shaft oring is made of polyurethane. I suspect this o ring has suffered from extrusion failure ( where it gets pushed into the tiny gap between bearing housing and damping shaft and damaged) and is letting oil out and air in. The fox air chamber oil is a very thick blue oil, circa 90w, known as "pillow pack" . I've seen brain shocks with a very thin oil on the damper body ( shiny shaft the air can seals to) that appears to be the damping oil.
My friendly seal shop that does hydraulic parts and repairs sold me high quality Parker polyurethane orings.
Part of the final how to, when I wrap this all up, will be part numbers of orings.
I've understood all of about 3 words you've said here, but it looks really interesting, so definitely subbing
I honestly never knew suspension could be so technical, why can't they just have it with a spring and a few bits of metal. No air to worry about, no oil to worry about hahahaI've found it immensely interesting working through the solution, it's slowly taking shape, at 1 hr a week I'm pushing Xmas I think. I will shoot a video of disassembling a shock with explanations, and of the actual vacuum bleeding.
You mad scientist you.Using a vacuum to pull liquid against Gravity is very cool. With -1 bar vacuum a cup of water was violently sucked into the chamber in under 2 seconds.
You mad scientist you.
So almost ready for the service?

Yeah, SID WC carbon with worn stanchion. Which works just fine, but ultimately I might use the Brain fork "chassis" with the WC internals.
Anyway, I do think my Brain damper needs a service. When you are ready
I really like the brain on the rear of my Epic.Ive a top brain adjust fork on the way to add to the collection.
