Had the car MOT'd on the freebie from Audi, and the it passed with only a couple of pick ups. One being the the rear pads and disks are close to being 100% worn. How easy is it to change these or is there some special tool needed because of the handbrake connection. I know from when i had the LCR you had to have a special tool to wind the piston back in are the Audi's the same. By the way its a 2004 1.9TDI Sport.
