you definately need to re-bleed the system. It's not hard to do by yourself it just takes tome finesse.
Put a latex glove on your right hand and have your wrench on the bleeder crack it open and make a cup over the cylinder with your palm and push down, (this forces the fluid through like normal bleeding(kinda)). Then close the bleeder pump the pedal a few times top off the fluid and repeat till done.
