As I stated in the original post, the car was sitting without being driven for about a month, when I went to drive it the brake pedal went essentially to the floor but I was able to stop the car, obviously I proceeded back to my diveway, but thanks, I guess I will try the master cylinder first since there is no obvious leaks and the fliud level is good an the hoses and lines all appear to be in good condition. I just hate to put too much money into a car with 279,000+ miles on it even though it still runs good and has been dependable.....maybey its time to put it to rest.

Thanks again fo all the suggestions.

Andrew, it does indeed sound like a master cylinder. You can change it yourself for under $75. If you don't have one, buy a Chilton'* 28200, and follow the instructions. Follow the bench bleed instructions that come with the new cylinder, and bleed your brakes when you are done. Search this forum for bleed instructions if you are unsure.

That price is reasonable.
Thanks again for all the info.
Happy New Year to all!!
