Answers :

Air in the line still your not using a one man bleeder are you.? have some one pump and you bleed the line or first bleed the mastercyclinder, get some on to help you have them pump the brakes and bleed a line to the master cylinder 3 time in a concession and do the next line line ands see if the goes up and give you a solid pedal.
Sounds like you hit an air pocket in your brake line and you probably need to bleed your brakes. to bleed your brakes you need 2 people and you go behind the brake caliper and pull off a grease zurk looking little bolt and then the other person pushes down on the brakes and holds them till you put that bolt back in and repeat till solid fluid comes out of the hole with no air so you are going to need more brake fluid while your doing this and you need to start with the rear right tire first then the rear left tire then your front right tire then your front left tire you always start with the furthest one from the brake booster and work your way closer. hope this solves your problem
