Look for a disconnected line/hose or even a cracked vacuum hose that you might have dislodged when working around the master cylinder.

I know filling it didn't do it, I'm just giving a time frame. I did not bump anything while doing it I don't think...I looked a little. I will look more thoroughly and get the code checked after school which is over in half an hour.

Well, I didn't get the CEL checked after all, but I did check the vacuum and it'* low. I mean it was at 9 it was really low. So there'* a leak. I was talking with a professor from Senior automotive at the school and he said since I help him and his department out with computer stuff (I work for user support) that he would help me out. He said he would get my car in and check it out tomorrow. So hopefully it will be fixed tomorrow or Friday before I need to go home. I will update you guys on exactly what it is tomorrow. They will be able to fix the brake line for sure if not the vacuum leak too. If not, at least I will have brakes to get home and probably know what is wrong so I can fix it.
EDIT: I also checked all the lines I could see easily, some weren't in all the way, but that didn't help at all.

Well, right now it'* parked on the other campus where I go because I didn't feel save driving it here, I will look tomorrow morning. Like I said it will be checked out, and since it'* the school doing it'* free labor, they can't charge. You only pay for the parts and those are at cost.

Well, they decided to do the engine stuff first rather than my brakes so I had to drive it home that so I could get it fixed. So I am without my car for a week . Anyways, the codes ended up being MAF sensor, misfire, and something with the EGR valve. Apparently my EGR valve got stuckl open. I had to get it replaced, it runs good now. Also I can say they are super bright, they tried telling me the MAF code was due to my cone filter and that it would never go away as long as it was on. I knew it was from the EGR valve and that filter would not do that...duh! All is well for now, it runs well and it is going to get fixed.
