Hi I am looking at a relatively high-mileage RS4 and am trying to work out what it needs, including whether it needs new discs/pads. I asked the selling Audi dealer whether it did and got the following info in reply: Front Brakes: - Off Side Disc 34mm (limit 32mm) - Off Side Pads 14mm (limit 7mm) - Near Side Disc 33.2mm - Near Side Pads 14.21 Rear Brakes - Off Side Disc 22mm (limit 20mm) - Off Side Pads 14.6mm - Near Side Disc 22mm - Near Side Pads 14.8mm This doesn't mean a whole heap of much to me, but I think I interpret it as meaning: - pads are fine. - front discs are fine. - rear discs need replacing pretty soon. So is anyone able to kindly interpret for me exactly how much life that means the brakes have left in them? Many thanks!
