What's going on? (brake question)

I just reached in there and felt around with the tip of the screwdriver till I found something that felt sprind loaded and pushed it a little, then held it there and backed off the adjuster.

Sorry, I don't know how else to explain it.
Maybe you could see more if you used a nice bright light?

yah. Thats what I remember doing in the past also.. It should be alot easier than I am making it. I was just wondering if by chance I was going something wrong though..Appreciate the help though! and yah, I used a good light, and have the car up in the air. Still cannot figure out whats going on.. at certain angles, my U-bolts/shock plates get in the way, so I've just got to figure it out somehow.
