Help me fix my brakes

[Hunter]

So I just changed brake lines in the bmw and a funny thing happened while I was bleeding them afterwards, the master cylinder ran dry. :x Basically it was a miscommunication between me and the guy I had pumping the pedal. He thought I said to keep pumping while I went inside to grab another bottle of fluid when I really wanted him to stop.

So now when I pump the brakes it's not sucking in fluid and I'm sure it sucked in a ton of air. Anyone know how I could fix this? Am I going to see a new master cylinder in my future?


This sucks.
