Thanks Cudamark, i'll give that a shot.
Truthfully I read the factory Haynes manual - it shows a single access hole example. The diagram size for the drum is small, doesn't show release direction of lever or direction to rotate to release the adjuster, so it's not super helpful.
Even with a super bright shop lamp up close and my wheel turned to lock for some visibility its tough to see inside the access holes at the parts so im going off of feel mostly. I'm sure when I get some time with it later i'll figure it.
