In my day they consisted of a pulley system forcing hydraulic fluid through
orifices. These orifices were adjusted to provide the right decelerating
force for each aircraft type. 

I seem to recall that a disk brake system was proposed. I don't think that
this was implemented in Royal Navy carriers, but may have been for modern US
carriers.
