[s-cars] Brake pedal firmness

[Dave Ellis]

The short answer, yes.  I've noticed the same issues.  After driving my 
wife's A4 the first stop in the S4 usually induces thoughts along the 
lines of 'for the love of god please *stop*'!  Seems like I have to use 
a lot of pedal pressure.  After one or two stops my foot recalibrates as 
you said.  I found the same after driving a number of other cars and 
coming back to the S4.

I'm hoping a planned upgrade of the brakes will fix the issue.
