I have a favor to ask. I am possibly picking up a 97 Chrysler Sebring for dirt cheap ($300). I guess it has been sitting for over a year, because the brakes are completely out…To me is almost sounds like a busted brake line, or no fluid in the master cylinder (but could it really be that easy?). I was wondering if anyone had a schematic or diagram that I could use to trace out the brake system. If I can get her running and stopping (lol) I will buy her.

Also if anyone has any other suggestions as to why the brakes are out, I would appreciate any suggestions.

 

The brakes are divided into two systems, so a broken brake line should affect only two wheels (diagonally on the car). If the pedal goes completely to the floor without effect, there's more to the problem than that.
The good news is that brake systems are generally pretty simple, and you can probably fix it without a huge expense if you can take your time to analyze the problem.
You might want to pick up a shop manual or a Haynes manual for the car to help you decide whether you have the tools and know-how to do the job.
