Guessing you aren`t that experienced with any cars? Changing pads is pretty straight- forward. But remember that if you are an absolute novice brakes are not the best place to start ! Follow instructions from RAVE manual. (downloadable from this site). Make sure you have all tools before starting. Torque wrench advisable, anti-seize gunge for replacing wheels, good jack & axle stands, somewhere level `n` firm to work. Check discs for wear/scoring. Is that enough of an answer or have I mis-understood query?
