Abs does anyone's work

yeah so yours is the two wheel system then.
The pump still supplies fluid to all 4 corners and you still have a sensor on all 4 but if for example you lock up the front right, both wheels on that axle will modulate identically regardless of if the front left has locked or not.
ph3 EBD is different. that can modulate every single wheel individually allowing turning under heavy braking and it does make a big difference!
