What Andrew said, grab a helper & bleed the air out of the new hose so there will be way less air to bleed out of the caliper, as they can be a pain. I have a helper pump the pedal vigorously 3 times then with good timing open the bleeder on his 4th downstroke to expel agitated fluid/air out of there. helps to put a block of wood under the pedal to limit the MC cups travel to its normal travel worn area (not a dealbreaker but it helps) & helps him better control the pedal.
