no experience in J4 maintenance. Any hints on oleo refills? Heel brake master cyl. maintenance? The rest looks like J3 stuff, but I am still looking for hints. First annual isn't until January.

Talked to the guy who did the last four annuals. He said "hey, it all worked, so I didn't mess with it."
