Brass works, so does mild steel. Just stay away from hardend punches.

Getting the rotors off without a vice will be a pain. The bolts are usually locktited in (for good reason!), and we break them loose with a hammer impact before going at them with a long breaker bar.

You don't need a huge vise -- just find a way to hold the rotor so that most of the leverage is applied to a stationary part.

Air impact works the best, of course......!
