Default 2002 century mushy brake pedal

ok so during the summer i drove my moms car, and the front left brake was grinding against the rotor, and i decided to do all the brakes, and replace the hoses on the front because i thought they might be shrinking on the inside like my old neon did. anyway through a seires of events (lots of seized fittings) i ended up changing the rear wheel cylinders and the calipers on the front also. while we were bleeding the brakes we basically flushed the system getting all the bubbles out i noticed the pedal was somewhat mushy at the time but everyone told me its just the brakes wearing in because all the surfaces were new. anyway my mom told me today her tire light was on so i just drove to where she was at threw her my keys and told her to just go on home ill put the spare on and be there soon. after i got the spare on i headed home and almost rolled through the intersection the pedal caught me by surprise so badly. you can literally push it more than half way down before ANYTHING happens. on a back road i tested them to see if maybe im just used to the stiffer pedal the park avenues have, and i mashed it as hard as i could from 70, and the abs never kicked on and the tires didnt even chirp. granted, the car did do a nosedive and stopped me in a "reasonable" distance but if that was a kid or a dog or something they would be dead. i checked the fluid and it was full, even at the sharpie mark i made in august. i also noted the rear drums seemed to be making a significant amount of squeaking. the type of squeaking drums make when theyre wet. but like i said the fluid was full. im stumped here. im thinking master cyl is about the only option but with my dad not able to work and no income at the moment i dont have the money to troubleshoot by buying parts.

any help would be greatly appreciated.

on my 99 yukon i had trouble getting a good petal, i asked a mechanic i know what was going on and what he told me to do is turn the key on when i was bleeding the system because of the abs module. i had to do this 2 or 3 times. also the drums should be adjusted from the back with the drums installed. i couldnt get it like it was but he said i got it as good as you can get. it stops good and the abs works.

Here'* a test for you. If you pump the brakes does it get firm? If so, the master cylinder is fine and you have air in the system. Bleed them again. Be sure to have help. Open one bleeder, have someone pump the brake several times. On the last pump have him hold the peddle down and you tighten the bleeder. Move on to the next. make sure the master cylinder stays full.

well, it does get firm but only half way down. as for the bleeding, i was behind the pedal but he was using a clear hose submerged in a mason jar of fluid. but when it warms up ill try again.
