Gentlemen: I had my brake pads replaced by a shop about 100K miles ago. Now I was just given a complete set of Kevlar/metal pads that I would like to install myself on my C280 Sport which has about 200K miles on it. I would like to know how difficult this job is? And is it similar to the DIY instructions shown on the DIY portion of this web sit for an E320 or 420.,whichs is pretty simple. If this job is similare, I have all the tools, heated garage and a good grasp of mechnical knowledge , I think. I have a power brake device I bought am I am eager to do the whole job myself.What say you?
