New Brake Bleeding
You're gonna need huge legs to push a brake pedal using a mc with that big of a bore. In the case of master cylinder bores, bigger is not better!
As for bleeding, easiest way I've found is just use gravity. With the car level, set up your catch-can and crack the bleeder open. check the mc fluid level every ten minutes or so while you work on other things. after an hour or so, close it up and move on to the next wheel. Works great!
