Last weekend I also did my front discs and pads following the wear light coming on and then being bombarded by my dealer saying I should book it in.
Bit the bullet and decided to do them myself. Slightly different route but as my original discs have lasted 6 years I knew it was now or never to get something I've fancied, I went with Zimmerman perforated Z coated discs and Ate ceramic pads (less dust I hope). Gave myself all day to do it and gave the calipers a really good clean and servicing. I must have hit Autodoc at a good time as I got the discs for £82 each and pads for £113. So far so good, feels good no horrible noises.
Now makes the rears look like they could do with some loving!
