This time I cleaned the surface of everything with scotchbrite pad. I want the primer to stick better in case I decide later to paint some of these parts. I degreased and primed.
I also looked at drawing to make sure I wasn't forgetting anything and I noticed all the penetrations. I won't do them now. I'll wait until I know for sure what penetrations I'll need. The plan never says to mount this brake reserve shown on the drawing. So I'll wait.
