I will never use mercedes OEM brake pads again.. I use "mintex" brake pads, they are made in germany as well.. the oem pads lasted me around 20k, whereas my mintex I'm already driven 20k on them and I still have 60% brake pad left.. Also the brake dust is greatly reduced.. If you can't find them I can send you a set.. I can get them for a good price.. you change the rotors when they are below service spec.. you can search the forum for the minimum service spec..
