I have a 1998 Honda CBR 600 F3, and I want to replace the break pads myself. Is this feasable with the service manual and some mechanical knowledge or should I go to a mechanic. The bike looks like it has two disks on front, so does that mean I need to buy two break pads? what are the best break pads organic, magnesium composite somethings, or something else? where online should I buy them? thanks.
