K/H disc brakes - hub replacement - studs

I am actually pressing the studs into the rotor and then pressing the studs/rotor (as a unit) into the hub?
Yeah, this question.
And what if you do not have a press, is there a safe way to get it done?

Also, certain rotors have to be ground down or they will wear through the piston seals.
Bendix or Centric, I forget.
