[urq] Brake Judder

[Ingo Rautenberg]

Martin,

I think you mean "Shudder" but in any case any loose/worn suspension  
components will make the situation worse, especially when braking  
from higher speeds.  Can't comment specifically on the Subi, but I  
think you're on the right track.  You state that there is a slight  
hint of this at higher speeds even without braking -- maybe tires not  
perfectly-balanced as well?
