Ok 1st thing is you will need to wind back the pistons which needs a tool to do this DO NOT push them back the same as the front ones damage will be done there is 2 types of rear disc on 307sw if the discs have retaining screws same as the fronts its ok removes pads remove caliper carrier off rear hub think it torx55 remove the securing screws and refit parts removed but if it does not have these screws you will need special tools as the disc is integral with the rear wheel bearing
