Brakes went out and the car died.

I got a 91 mustang and since I bought the car its had a hissing sound when i hit the brakes.(at idle when i put my foot on the brake the rpms would go up) so I just put v8 brakes on it last week and tonight I was driving and I went to hit the brakesa and the pedal got super firm and as i continued to press the brakes harder cause the ebrake doesnt work I thought to my self maybe ill fix the ebrake tomorrow if i get this thing to stop lol...no no back to what happened I hit the brakes and as it was slowing down slowly the car died and now it wont start up. Is this the brake booster or something else?

Could be that you have a major vacuum leak in the booster, although it seems odd that that would keep the car from starting.

At any rate sounds like your booster bit the dust.
