Default Semi-Emergency...brake problem. UPDATE

After getting home from work and parking my car in my driveway last night, applying the Parking brake as usual, I went inside for a minute. Came out and started the car to move it to the top of the driveway, released the P-brake, put it in D and rolled forward. When I tried to stop the brake pedal hit the floor in less than a second. I had no pressure.

I said a Hail Mary (not really) and went to work this morning and drove even more like an old man this time hoping not to get into an accident. But I can't walk since it'* a 40 mile trip.

As to why this happened after parking the car and so suddenly I have no clue. Brakes are one thing I haven't worked on and don't know what the problem is. The fluid is full and it'* not leaking as far as I can tell!

I drive about 85 miles a day and need to get this fixed asap. Thankfully it'* not a Monday. If anyone can point me in the right direction I'd really appreciate it. Thanks guys.

84 to 91..is the direction you want to go. Get off at 47E... friendlies live close by.

Sounds like a master cylinder if there is no fluid visible and the level isn't dropping.

Why use the parking brake on an automatic? I know a few people how do this and I can see it with a standard shift. Doesn't the tranny lock up the drivetrain when it'* in park?

I use it because my driveway is on an incline.

Jim had it fixed when he had the car and it works great. It'* not going to snap anytime soon.

UPDATE:

As Bill stated he thought it was the master cylinder. After inspecting for leaks and found none, I got a new MC and Bill and I installed it in no time. It turned out to be really easy as neither of us had replaced one before. I didn't think to take pics of the process, but it was pretty much done with by the time we thought of taking them

And at 107,000 miles, mine had already been replaced before too.
