摩擦系数只与摩擦的两个界面的材质有关，忽略微小因素，抱死与不抱死的摩擦系数是一样的，车向前的惯性力是一致的，所以唯一的区别就是刹车力的不同。很显然，抱死的力要比不抱死大。
The coefficient of friction is the same for this discussion.
The friction force is different regardless static friction, kinetic friction and rolling friction. This is because of the difference of normal force caused by gravity center shifting during braking.
During braking, the force involved is way more than friction force, normal force and friction coefficient.
Personally, I have not done any research regarding the difference of ABS braking distance or normal braking distance. However, to do all the math and engineering for this problem, I don't believe any of us here will have the ability to do it due to the complex element involved.
I am not trying to deny the degree that you might have or mine. Just like wind tunnel test, there are only hand full people can do it without using accessing super computer. Even with that, a lot of these are experimental.
