Abs!

[EFI69Cam]

What does the ABS work on , foot on brake as long as sensor sees the wheel moving does not kick pressure off pad wheel stops foot still on brake kicks pressure off pad, why would you need weight of car as long as its close to donor car due how would car know if you had 1 ,2,4,5 people in car and fully loaded with cases etc, wheel dia I think would not come into it, look at all with modified wheels ie bigger on cars with ABS.

I have made this argument. I think the vehicle stability functions are getting confused witht the ABS functions.

Each channel is monitored separately for spin during a braking event, if the wheel locks, pressure is modulated to induce spin.
The only time speed differentials between front and rear would matter would be in a traction control system where slip would be a difference in the front and rear sensors, but then again they might do it by looking for an improbable increase in speed.
