I have a similar issue in my 2001 A6 q.... Occasionally when I stop say
from highway speeds like and offramp.... I get what is a horrible shake
in what feels like left front... I let of brakes and re apply it goes
away.... Because it rarely happens at in town speeds and I'm so used to
how to stop it I guess I don't pay much attention to it now but this
thread  got me thinking... Anyone have any thoughts? My abs is out as
well... Tires good pressure and not worn no other shakes or vibrations..
It's like light brake pressure at 45+ causes it if its slow speed...
Won't do it ... Ie parking lot or something.
