Service Brake

if you have the SBC brake system E class 2003 and up till 2010 and your car has higher milage the SBC hydraulic unit might need replacement they "time out" and Im pretty sure its covered under a special Benz warrany for a long period of time. could also be a brake light switch fault.

Holy Cow! No chit??!!! What's the thinking behind that? I bet they don't tell you that when you buy the car.
