Nope, no ABS, they just seem to be using it for power assitance.

The upper forward facing plug is a 5 pin, although the wiring only appears to have 3 pins.

The motor itself is a flat 2 pin affair.

The upper 2 pin isnt used.

I dont see any other wires going to it, but access isnt great.

The brakes were working when my friend got the car. But its been sitting parked up for nearly a year, only having been moved a couple of times during that period. Although last time 2-3 months ago, pretty sure the brakes were working.
