Hi you will need a suitable diagnostics unit which has the facility to put the car in to rear lining change mode, this is used when you have the car jacked up and the rear wheels off with the car in gear so it wont roll, switch the handbrake off and engage rear lining change you will hear the motor retracting the pistons, then with the aid of a beefy screwdriver inserted between the old pads and disc gently push the calliper piston the last bit back into the calliper the pads should be moving free now so its just a case of undoing the two bolts that hold the middle of the calliper to the main carrier these are attached to the slider pins which have a rubber boot covering them and allow the calliper to self adjust to compensate for wear, once released from the slider its a case of pulling the calliper away making a note of which side the wear indicator wire sits, you will have to replace the wear indicator as well as the pads, the wear indicator has the plug end in a slot in a metal bracket which you have to twist to release it so you can separate the plug and fit the new wire, make sure you fit the new pads the way the old ones were fitted that makes sure the cut out for the new wear sensor is on the correct side, take photos as a reference, clean the runners for the pads on the carrier with a stout wire brush and then coat them with a thin smear of copper grease and then mount the pads on the carrier and gently push the calliper body over the new pads, you will have to push the slider pins in a little to allow this, you must always use new bolts to hold the calliper to the carrier but in saying that you can get away with using the old bolts provided you clean the threads and use a blob of blue thread lock, do not over tighten these bolts as they will snap, nipped up will suffice say 20nm, once its back together give the brake pedal a push then take the car out of lining change mode then engage handbrake and replace the wheels, don't think I forgot anything but claim poetic licence.
