i just changed mine today. same way u change car brakes. u gotta take off the 2 hex bolts, slide out the caliper, the on the oposite side where the hex bolts was is two 12mm bolts that holds the pads in place. remove that, the the pads will slide out. now on the pad that was on the INSIDE, theres a metal plate on that pad, take that off and put it on the new one. now use C clamps to squeeze the caliper in. (this is gonna tricky) when u get the pads in to fit over the rotor dont bolt it up yet. buy brake pad grease from the auto parts store. $1.34. now grease the surface of the pads, bolt it up and good to go. i didnt even have to bleed my brakes. but it may be necessary. so dont take off the brake line. hope this helps I:I
