Now I have anoother problem my brake pedal is hissing as well as very hard to push. Along with the Anti-lock light staying on after the system check. Any help out there??

Sounds like the power booster going south! The hissing is probably a vacuum leak as you apply the brake pedal. A stiff pedal or hard to push can indicate a lack of vacuum assist.

Man I just replaced that about 3 years ago. If so I guess I better try and do it myself this time. The labor charges are outrages. Any suggestions on replacing the booster?

You can do the booster at home with common tools. I always found it easier to remove the drivers seat. There are two nuts on the inside. They're difficult to get to and you need arms like Stretch Armstrong, but you can get to them. Good luck.
