I'm getting closer to to road ready on a '82 CB750 Custom. The previous owner had let the bike sit, but his brother installed a new plastic brake reservoir on the brake lever and gave me all new front brake lines (all the way down to the calipers). Installed those, but their full of air at the moment.
My question is: How do I tell if the brake lever piston works correctly (good seal)? It moves freely (under spring pressure) via the lever or even when I push on it with my finger. I don't want to remove the piston if I don't have to (not sure I have to right tool to get the clip out). I don't live close to anything, so figure I should ask first.
The dust cover on the piston looks to be in great shape, it's even possible it's already been rebuilt.
However, with fluid in the reservoir, no brake fluid comes out of the brake lever brake hose connection (hose is disconnected). I can see the piston move back and forth, but there's no brake oil coming out.
I don't know how to safely remove the plastic reservoir either (should I need to, to inspect the oil holes). Does this just snap in and out?
