Help please

Well I was putting new brake on yesterday and today. Finished the Job and went to start the car. Pumped the brakes to build pressure in the system. All is well pressure is back in the pedal and then I here a pop. Pedal goes 90 percent of the way to floor. Fuck me. Turned the car off, checked under the hood and look at the master cylnder, fluid everywhere. Looks like all the fluid came out between the master cylinder and the power brake unit. Also the passenger rear SS brake line popped. Fixed that bled the the brakes. Brake pedal is nice and firm again. Turn on the car pedal goes almost to the floor again. And I get a nice sucking sound coming from the problem area.

Any Ideas.

did you disconnect the booster line that goes from the MC to the intake manifold? it has a check valve in it, and if you put it on backwards it can put too much pressure into the system. (ask me how i know)
