Odd how some have had problems with the EBC's and some not. I just installed the EBC greenstuff pads on my wifes 00 C230 about 2 months ago and so far they have exceeded my expectations. Virtually no dust and not a hint of squeal. When I installed them I used (can't remember the name) an orange colored substance for brakes to stop squeal. It must have worked because they are dead silent. I just wish they made them for the rear brakes which I installed ATE's. They dust up BIG TIME!! Looks weird after a few days because the rears dust up and the fronts don't!!
I'm going to install the EBC's on my E320 when the front pads wear out, can't wait because I hate the dust on my wheels.
