Recently, I needed to change brake reservoir grommets (failed inspection for leaking brake fluid). The first part was fairly easy with a turkey baster and a little prying.

My question is what is the best route to take for cleaning the brake system? I've cleaned the reservoir with brake system cleaner but it still is very cloudy, and even black in some areas. There are so many nooks and crannys on the reservoir that I believe it will require replacement.

Should I install the new reservoir before purging the system? or, Should I purge the system with the old one installed and then replace it after the system is flushed?

I'm reluctant to install a new reservoir, purge the system and end up with a new ruined unit. Is there a good method for cleaning the old one?
