I thought it may be mentioned that master cylinders can be a bit hard to get the air out of. If everything is good inside after the honing and re-sealing, fill it up with fluid before putting it back on the car. Push the plunger in and out until the fluid comes out. You may have to hold your finger over the exit port on the retraction of the plunger if it tries to suck air back in. If you are a packrat like me you could also hook a short piece of brake line on the port and and stick it in a jug of brake fluid, that way if it sucks anything back it will be fluid. Bleeding brakes works really slick if you put a clear plastic tube on the bleeder and in the fluid. Same principle.
