It is pretty easy...just did it last night - use TORX tool to remove two carrier (caliper) fasteners (bolts). Pull up caliper from bottom - be careful not to lose "rails" that pads travel on. Pads are retained in carrier by "dimples" on pad that drop into holes on carrier. Remove the pad attached to hydraulic cylinder last...just pull it straight out - held in piston by three spring pressure prongs. Compress piston with C Clamp before reinstalling new parts. Reverse process. Study parts...install is pretty intuitive. Hope this helps...by the way, I live in Ellisville, MO. Have you ever changed out parking brake shoes...having fits with this and can't seem to get it right???
