Did you try bleeding the brakes? Sometimes, they will just have a little pressure and then when you bleed the air out, you will get more pressure.
To take the master cylinder apart, remove the brake lever and then look down inside where the brake lever was pushing. There's a small snap ring down inside there that you have to remove. Once you get it out, the other parts will come out.
