The method described below worked for me. I am not saying it is the only method to complete the task. I will not accept any responsibility for damage caused to the vehicle as a result of following my guide.

- STEP ONE -
With the car in gear and handbrake off, loosen the wheel nuts on both the rear wheels. Use a trolley jack to raise the rear end and support it using 2 axle stands.

- STEP TWO -
With the car raised, undo the wheel nuts and remove both rear wheels. This will leave you looking at the rear brakes and discs. At this point check to see if the pads need changing.

- STEP THREE -
At the back of the calliper facing the rear of the car there are two bolts, one at the top and one at the bottom of the calliper. Using a 17mm socket, remove these two bolts which should allow you to slide off the whole calliper from the disc. Remove the calliper and place it to one side, making sure you dont put it anywhere that may contaminate the pads. Now you will be left looking at the disc itself.

- STEP FOUR -
In the centre of the disc is a bolt holding the disc to the hub. Use a 30mm socket to remove the bolt. A lot of force may be needed to remove the bolt, as they are on tight. Once undone, slide the disc from the hub, pulling towards you. Again this may prove hard work as they are on tight.

- STEP FIVE -
Now you need to wind in the piston to accommodate the width of the new discs. Using a thin screwdriver rested through the slots in the piston, begin to wind it in. You should start to see it moving inwards towards the hub.

- STEP SIX -
Clean the whole area and slide the new disc into position, with the bearing side facing inwards. Using a 30mm socket replace the bolt holding on the disc. This needs be done up very tightly.

- STEP SEVEN -
You should new be able to reposition the calliper you removed earlier over the new disc. Make sure the the notch on the inside pad lines up with the notch on the piston, this will allow the calliper to slide on fully. Replace the two bolts that hold the calliper on, one at the top and one at the bottom. If you need to change the pads, do so at the beginning of this step.

- STEP EIGHT -
Repeat steps 3-8 for the other side of the car. Make sure the discs spin freely, you may hear them rubbing on the pads. Now press the brake pedal all the way to the floor, and continue pumping it until it feels solid.
- STEP NINE -
Replace the wheels and tighten up all the wheel nuts. Remove the axle stands and lower the jack. Put the car in neutral and apply the handbrake. Thats it, the discs will take a couple of hundred miles to bed in properly.

I hope this helps some people. I dont claim to be a mechanic... in fact i hardly know much mechanically about cars at all. This is why i made the guide, to help other people in the same situation as me.
