Power/Manual Brakes?

So if I go manual with the MC I have, should I be good for a while?

MC I have new in box...

should be fine. is that a dics / drum or disk / disk MC?
also, like you say, you'll need to make or buy the 4 bolt / 2 bolt converter and source a manual peddle rod (last one i got on here for around $20 shipped)
