Full titles differ between systems:

IPC:

Brakes with substantially-radial braking surfaces pressed together in axial direction, e.g. disc brakes > with a plurality of axially-movable discs, lamellae, or pads, pressed from one side towards an axially-located member > without self-tightening action > Brakes with a plurality of rotating discs all lying side by side > actuated by a fluid-pressure device arranged in or on the brake

CPC:

Brakes with substantially-radial braking surfaces pressed together in axial direction, e.g. disc brakes (similar clutches F16D13/38) > with a plurality of axially-movable discs, lamellae, or pads, pressed from one side towards an axially-located member > without self-tightening action > Brakes with a plurality of rotating discs all lying side by side > actuated by a fluid-pressure device arranged in or one the brake

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
