One never does. If one did, they would not be called panic stops. Take it
from one who drives as defensively as they come, you can never anticipate
it. Even if you are taking every precaution. Beside, you are probably
more likely to have a panic stop in town where some kid or dog jumps out in
front of you than on a freeway.

No. Many people do it. I did it for years. In fact, I really got to like
that firm pedal.

Yes. But, I think there might have been some overlap. In any event, the
stock SV MC was too long for my Webers. So, I had to get a shorter one.
The only one I could find was smaller. A smaller MC makes for a softer
pedal. So, I took off my servo and am happy with the results.
