Nissan Repair: Replacing Rear Brakes, 2003 nissan altima, nissan altima

Question
Just replaced my rear brakes in a 2003 Nissan Altima 3.5
I compressed the calipers (hopefully they weren't the turn type) installed new pads and rotor and now my brake pedal goes to the floor - pumped it many times with no response.
Help!
Thank you!

Answer
Lucky for you, Denise, they are the push in type. It is fascinating how many women are doing work on their own cars! Ok, well, if you tell me your step by step method of doing these, we might come up with something. But let me ask, did you open any bleed screws either on the master or on the caliper?
