What promted me to do the brakes was a horrible grinding noise coming from the back end.So after purchasing some new disks and pads it's off to work we go.First thing to do is put the car in neutral with the park brake off and front wheels chocked.Jack up the car and support on axel stands.Unscrew the brake fluid resevoir lid and check the fluid level wont spill anywhere when retracting brake pistons.Removing the wheel will reveal something like this.
Remove the 2 brake pad retaining pins by using a small drift or flattened off nail.The spring clip will now fall out.These will not be needed again if you have purchased new pins and clip.
The pistons will have to be retracted,I used a wrench.One side against the old pad the other on the outside of the caliper and squeezed them in.Then wedged a spanner in between the old pad and the old disk so they didn't move when retracting the other side.Again check on fluid level?
The next thing to do is easy,Using a 17mm ring spanner (a socket wont fit in the space available)undo the 2 caliper retaining bolts and discard.Cus hopefully you have bought new ones.When its off just secure the caliper safely so the brake pipes aren't strained or kinked.Then undo the retaining screw on the disk itself.
All that needs to be done now is to remove the disk by tapping it with a mallet around the outer rim and turn 90 degrees with each hit.Should take about a dozen or so hits to dislodge it.If its very tight you will need to slacken off the park brake by inserting a flat blade screwdriver into one of the wheel bolt holes and turn the adjustment knob inside the hub to slacken off the brake shoes.
Then clean everything out REMEMBER ASBESTOS HERE
This is the state my disk was in compared to the new one.
Place the new disk on the hub and secure with the retaining screw.
Refit the caliper using your new bolts and tighten to recomended torque.Then as long as the pistons haven't moved the old pads can be taken out and the caliper cleaned.Add a little bit of anti squeel grease to the new pads (on the back and sides) and refit.
And not forgetting to put in new pad retaining pins and spring clip.
The wheel can now be refitted so work can commence on the other side
I did this job with snow on the ground,(Pic1)and it still only took about 3 hours (cus im double hard 
) Who cares if theres snow about and only 2 degrees out.
