I was reading the article and got to this "ABS systems donít rely on mechanical break biasing methods.
I stopped reading the article
Mech biasing is every bit as important.
If the bias is all F^&*&% up , anything below threshold, one end is going to be doing more than its share
That end will also be trying to lock up the wheels and relying on the ABS long before the other end is working to the full potential.
A number of the cars I work with have full on Race ABS and we still work with a balance bar.
