It is also possible that the rotor or pads have gotten contaminated by some sort of grease or oil, including finger oils.

Handle with gloved hands upon reinstallation.
Yep I have broken them in with a couple of dozen firm stops from 25km/h.
Both front and rear have very little braking power, and they had really crap braking power from the very first ride, so I doubt it is contamination, unless the factory contaminated it.
