Rear brake not activating

Just yesterday I pulled my Rocket X from winter storage, to find the rear brake pedal useless....Guess 7 year old brake fluid will do that..Not a big deal, will try first to change out the brake fluid, if not, will take master apart and service it....Glad i'm retired as now i have something to do...
 
It must be something in my garage!!, both rockets without rear brake???
