This listing is for a genuine Mercedes brake pedal pad.  Fits MANY models, including some brand new 2019 Mercedes vehicles.  Great grippy rubber material, and these generally last for a very long time.  I typically replace them each time we do a brake fluid service on cars, or once every 2 years.  Free and fast shipping from a Mercedes repair shop that's been working on these vehicles since 1985!  Happy to support with install questions related to this part or otherwise.  Thanks!
