With a life time warranty and you taking the time to both correctly clean the black sludge out of the resivoir and bleed it fully , it'll prolly be fine for decades .
When I did used cars , I occasionally used used master cylinders as they're well over $100 new and this beats up the profit margin . no worries , I never had a failure nor come back .
Some times I bench bleed but not if the underhood paint is nice .
I use a $50 tank typ pressure bleeder , it works great and only takes 15 minutes tops to flush and bleed out the entire system , you are correct , when the brake system is bled and has good pads , the power M-B brakes are a bit touchy .
One of these days I want to try speed bleeders .
Yes , ATE , Girling and Bendix all supplied brake parts to Mercedes , just never have mis - matched on each axle and you'll be fine .
