Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** you for the question. These are some issues with the master cylinders on this vehicle. The majority of the issues had to do with the fact that the master cylinders were not the correct ones that were installed from the manufacturer, causing a series of issues. There was actually a recall on these because of this. I would contact the dealer to see if yours was ever replaced under recall and if it was not then you may be able to get it replaced for free.
They will pick and choose which vehicles to cover depending on requirements. I would contact the manufacturer and get them involved as they are more likely to cover this.
