No. Brake system has separate light. The brakes are technically not failing since no code is being thrown.
Let's keep this survey on track. I want to know ONLY if you have soft, spongy brakes, difficulty stopping or excess travel in the pedal. If so answer "Yes" to this thread and also the year of your CHASSIS, not coach, would be handy. Then, with your VIN available, call 800-FOR MERCEDES (SELECT OPTION 4) and tell them about your brakes.
I'm in touch with MB USA and also have a service appointment scheduled Oct. 8. I'm attempting to go to bat for me as well as all the other owners with this issue, too.
I'll report the results of my service visit here on the forum after October 8.
