I was checking the brakes on my 2003 E320 that just turned over 98K miles. I've got a "BRAKE", - Brake Service, on my dash.


My brake pads in the front look great and the pads on the rear are less than halfway, so I'm good.


My question is now, How many brake pad sensors are supposed to be there? I have a sensor on both front pads but there is only one sensor on the passenger side rear brake pad. No sensor is on the drivers side rear pad.


Is that normal to have two in the front and one in the back?


Is there a brake sensor in the cars computer to tell you to check your brakes due to mileage?


My Range Rover check engine dash light came on at 82,500 miles. But I found out that the system just sends a reminder at 82,500 miles, nothing is wrong, it's just a reminder.


Does Mercedes have a mileage reminder other than "Service D" is due?


Thanks in Advance
