I have lived hear ten years, but this is my first car with rear discs.
Thanks for the encouragement on the DIY, but I am going to bite the bullet and take it to the dealer. I was keen to do the rotors and pads, but the parking brake seems like the sort of project that might get a little complicated and, with only one car in our household, I can't make any quick runs for parts or tools without putting the car back together.
