Define "ABS"

[int2str]

From the 2017 TT Rules:

 

E) TT4 Anti-Lock braking systems (ABS)
For TT4 only—Anti-lock braking systems may only be OEM or offered specifically for
the car model (any trim model or generation) as a factory option. No OEM systems
offered for a for a different car model or aftermarket systems are permitted.

 

What does "ABS" mean in this context?

The electronic ABS system?

Or the brakes in general (pistons, calipers)?
