Just had the 5 year MOT done. passed with a couple of advisories. 'Front and rear discs worn, pitted or scored but not seriously weakened'. front pads 10mm rear 8mm. cost to replace -front £527.82 and rear £451.96. Mileage is 28,000. now bearing in mind that the rear discs were replaced at 2 years I can't understand how the rear pads are more worn than the fronts unless front pads are thicker to start with. In all the years I have had cars I have never been faced with brake disc issues in a car of this age particularly as Audi are supposed to be quality cars. I have been reading some previous discussions and these prices seem well over the top. Do brakes need to be done by Audi. Could my local garage do the work? I read a comment, I think by Spike, that there was coding to be done for the electronic brake. I was also offered new wiper blades at £66.20 but I passed on that too. advice would be gratefully received.
