No Brake Pressure?... WTF? K, ... Double posting. I asked this in the Automatic Section but maybe someone could fill in the wholes in here.
"K, this is odd! ... JUST now, parked on a very small (barely visably noticeable) incline. And the car starts gradually rolling backwards even though I'm in park. Threw the e-brake and no difference really. WTF?!!! ... It's like she's in neutral but even if the tranny is craping out, why would the e-brake have almost no effect?
Posting in here because I would like to hear some thoughts as to why it's like 'P' is acting like 'N'. And if so, is there a simple fix.
If anyone wants to add in why the e-brake is having no effect, I'm all ears!
Stock 4L60e, 150K miles(roughly) .. & no previous issues with trans until now."
... Sooo, any thoughts? ...
Addition piece: For a moment, when I had my foot on the brake pedal, my foot sank!! .. Like there was no line pressure.

But why would it randomly act up now? .. I had the brakes 'bled' 4-5 moths ago. I'm just trying to make sence of it.

Sorry if I sound like I'm panicking. I just don't want to walk back out to my car and find it plowed into another car or blocking traffic. 
... I actually have a book titled Famous Last Words acting as a 'chuck' behind a tire right now. (ironic)
It seems fine now but I can't stand random occurrences! Drives me nuts!

Replace the amster cylinder. Its the only part that I can think of that I have had randomly lose pressure and come back like no problem. Start there and bleed the brakes again. Now if the shifter was in park I cannot explain why it acted like it was in neutral. The brake failure should not of caused this. Let us know what u find. And just for reasons your foot brake controls both front and rear brakes, the parking/emergency brake controls just the rear by a cable.
