When all the 4 wheels are braking,it seems logical to write the longitudinal acceleration like this-(adsbygoogle = window.adsbygoogle || []).push({});

$$m_{vehicle}.a_x = Sum of F_B $$

Where

F_B are the brake forces at the 4 wheels.

Now,what would the equation look like when ABS is working?

Some of the wheels would be braking while others would be accelerating(1.is that correct?)

Or,is it case in ABS that all the wheels are braking all the time?

I've read that the principle of the ABS is based on limiting the brake pressure.
