Brake Balance

[Grant Lenahan]

Not my experience, although the explanation sounds a little plausible - 
but only up to a point. Read on.

However, on more serious braking, ABS cannot do what you say and still 
have the car brake effectively.  braking grip is proportinal to weight. 
Weight in an Audi, on deceleration, will probably be 70% of more to the 
front.  QED.
