Late W116 Early 126 Brake Booster ( Used )

Good used working brake booster RECENTLY removed from W126 300SD with good working brake system. Appears to have been a replacement a few years back, but we have no idea of actual age or mileage. It is very clean inside, with no evidence of brake fluid contamination. Common failure part leading to hard brake pedal feel and difficult braking. Check to see if yours if full of brake fluid from a leaking master cylinder.
