Re: S6 Brakes, Please Help


Until I read your posting recently, I had in no way noticed anything
unusual about the brakes on the S6 that I purchased 10 days ago.  

I was paying attention to it today, but still couldn't tell anything
real unusual.  The travcel of the brake pedal from rest to full brake
pressure position is probably around 2 inches.  I believe that is
pretty similar to my previous car ('88 Porsche 911).  Maybe not quite
as easy to modulate, since the brakes only picks up slightly in the
beginning, and then picks up pretty fast, whereas the 911 brakes
seemed more progressive.  Full brake pressure is matching up
reasonably well for heel and toeing, though I may have preferred a
slightly shorter brake travel.  I have actually been real happy with
the performance of the brakes, but of course I have not yet pushed
them continously in a drivers event...

I will try our A6Q and let you know...


Seems my 911 had maybe a more progressive brake pedal travel, but 
FYI, my car before the S6 was a '88 911 Carrera, and my wifes car is a
'96 A6Q.
