Would like to know if anyone has any pictures or diagrams how these valves are assembled. Had a little hat shaped piece come out and I'm not 100%sure which direction it goes back in. Also upgrading the spring while it's apart. It's a valve for a 1987 with 4 wheel disc's.

I remember doing a search on this subject & located a company that would rebuild.
