There is a hall effect sensor on each hub, which inputs to a ABS ECU. Under normal conditions, they all give a similar reading.
However, when wheels are about to lock (as a result of hard braking) there would be a discrepancy and the ABS then activates.
This rapidly apply the brakes, giving the effect of cadence braking, which allows the vehicle to steer and brake simultaneously.
As Rich says, I suspect the sensor is the issue here.
ESC (i.e. traction control) also uses them as an input.
