Brakes feel like they are always on

My wife called me today and stated that this car felt like the brakes were on as she tried to drive to work. She parked the car and I looked at it when I got home. I noticed the battery light was on so I removed the battery and took it to get it tested. It was fine so I put it back in, drove it (just fine) to the parts store where they did an electrical system test and found the alternator was bad. I replaced it and tried to test drive it when it felt like the brakes are on. It doesn't feel like there is an issue with the engine where it doesn't have the power, it clearly feels like the brakes are on. I disconnected the ABS electrical connector under the hood, same thing. I pulled the fuse for the Cruise Control, nothing either. I did manage to drive it around the block and it started out fine. I could actually feel the car begin to slow about 1 block away as it seemed the brakes began applying and stayed that way. Any suggestions? I am new to this site but it appears it is a donation site. I will be happy to donate for a correct answer. Thanks.
