I’ve been standing at the door since yesterday with a new / used A6. when I tried it a week ago, I already noticed the jerking while braking. I made it happen at the contract signing and the really nice and helpful salesman promised a indulgence to get rid of the jerking. At the vehicle collection / test drive everything was fine. On the way home ( Hof => Frankfurt 310km ) I had the impression that with every km it was the i The brake discs are all very good, new blocks on the back, no new ones on the front, but in view of the fact that the brake discs are all very good, new blocks on the front, no new ones on the front, no new ones on the front, and no new ones on the front. I was not able to keep up with the speed of the brakes, I had to slow them down under the circumstances. He thinks they have probably been changed around with the discs and the blocks in the back due to the jerking. I still have a new car warranty until 05/2005. but it is 100% a wear part (which is not worn out). what would you do now? help?
