I am going to try and tackle installing my new cross drilled rotors and brake pads this weekend on my 99 C230K. I have performed the search function on this site and came across some instructions. But my question is, do I need any other parts (brake sensors, paste, brake cleaner, etc) when doing this job? My brake light has yet to light up on the dash. Also, is a change of brake fluid recommended at this time? Which one would be the best? Thank in advance.
