Gentlemen: I did not install the last set of pads on my C280 (W202) Was given a new set (kevlar/metal) and would like to install them myself. Is this a difficult job? Is this in any way similar to the DIY information shown on the DIY part of this forum? A good clear answer would be greatly appreciated. This car has over 200K miles and is in "like new" condition. The 1st set of pads lasted almost 100K miles. Any help on this matter is welcome.
