Yupp you will have to bleed them now. Hopefully you know how to do this. All you do is start in the back farthest away from the master cylinder and work your way forward from farthest to closest. While doing this having someone in the car. Tell them to pump the brakes then tell them to hold it, when they hold it loosen the bleeder valve a little and let it come out then tighten it back up with them still holding it. Do this as many times as necessary and do the same with the rest.

Just let a little brake fluid out at a time (don't let the pedal get to the floor). If you let the pedal get all the way down then it may suck up dirt and debris from around the outlet and that ultimately leads to early failure.
