Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Brakes with substantially-radial braking surfaces pressed together in axial direction, e.g. disc brakes > with axially-movable discs or pads pressed against axially-located rotating members > by moving discs or pads away from one another against radial walls of drums or cylinders > with self-tightening action, e.g. by means of coacting helical surfaces or balls and inclined surfaces > Mechanically-actuated brakes

CPC:

Brakes with substantially-radial braking surfaces pressed together in axial direction, e.g. disc brakes (similar clutches F16D13/38) > with axially-movable discs or pads pressed against axially-located rotating members > by moving discs or pads away from one another against radial walls of drums or cylinders > with self-tightening action, e.g. by means of coacting helical surfaces or balls and inclined surfaces > Mechanically-actuated brakes

No child classifications to compare. This is a leaf node in both IPC and CPC.
