Hi, can any one help? I have just fitted new brakes and discs on my Audi S4 b8 2011 when I brake at 90 to a hundred miles per hour I'm getting a vibration from the right wheel of my car at 1st I thought the discs were warped the dealers replaced the discs and pads for me but I'm still having the same problem it only happens when brakes are hot
