ML500 EATS THROUGH BRAKES. EL DORADO HILLS MERCEDES REPLACED BRAKES AND ROTORS ON MY ML500 AT 29000 WHEN I PURCHASED THE VEHICLE, SINCE THEN THEY HAVE HAD TO REPLACE THE BRAKES AND ROTORS 3 TIMES AND I ONLY HAVE 60000 ON THE VEHICLE AND MOST OF THAT WAS HIGHWAY DRIVING. I DO NOT PULL ANYTHING, NO TRAILER HITCH INSTALLED. APPEARS TO BE DESIGN FLAW OR I'M BEING TAKEN BY THE DEALER. *AK
