does anyone know if the 2004 c240 4matic has break pad sensors that will alerat me when they need changed?

thanks for the help.

 

I'm guessing your 2004 is the same as my 20005 as far as that goes...so....on mine, there is one sensor on the right
front only. No need for any on the rear since the fronts go before the rears typically, and no need for two sensors on the same "axle" since if one side is worn, the other would be as well.
