[s-cars] Brake pedal firmness

[Fred Munro]

Hi Wayne;

I transition between my S4, S6, a Camry, and my '93 Beauville van. I really
don't notice the pedal effort on the S-cars being unusually high. When the
rotors are clean, the brakes on both s-cars work quite well, actually; they
pull the car down quickly with minimal pedal effort. The pedal is high and
firm on both cars, but I spent a lot of time fiddling with the brakes to get
them in that state. If the rotors are rusty from sitting in the rain for a
few days, it's a different story....

All of the brake servo postings are encouraging me to ask a different brake
question.  I sometimes drive 2 other vehicles, and compared to those, the S4
has very light steering and requires more force on the brake pedal.  This
hasn't caused me any problem and the brakes seem to work just fine.  But
when driving the S4 for the first time yesterday after 2 weeks with a rental
car, I found myself stepping on the brake with what seemed like a firm push,
and nothing happened.  After 30 minutes or so I got myself recalibrated to
the brake pedal and all was normal again.

So my question for those who routinely drive other vehicles:  Does the the
S4 take significantly more pressure on the brake pedal than the other cars?

This isn't a case of no brake boost at all.  When doing the bomb depletion
test, the brake force changes from very firm to practically immovable.  The
pedal force has been the same for the 3-1/2 years that I've had the car.
