ABS is multichannel in the front, and also most modern cars have brake force distribution, so one side will be worked more at the limit when a corner is involved, and it's a function of traction. The other is heat, which has an impact on performance as well as wear. The hotter things get (and tire heat does impact local/ambient temps for brakes), the less performance, and therefor the more input. Kind of a downward spiral effect.

It really turns out for me to be traction correlated. You push on the brakes until you run out of traction....which tire(s) have the most traction?

A braking engineer is best to answer this question, I'm really just commenting on experience driving cars at 9-10/10s of their limits. .
