Help!!! No Brakes!!!

[QWIKWE4]

I was driving down the street the other day coming to a stop light and my brake pedal went all the way to the floor and the car didn't stop, does anyone know what part might cause this problem?

Is there fluid leaking anywhere? Usually a sudden failure where the pedal goes all the way down is a break in a line and the fluid just pumps out.

The fluid is full and there are no leaks anywhere. That was my first thought but after I checked that and there were not any problems I didn't know what to look at.

Next thought is maybe a master cylinder failure. Piston seal let go - can't make pressure anymore. I had this happen once but not as drqastic is this. Mine would just slowly push to the floor but I still had reasonable braking.

Get more feedback. Is it a powermaster?

Yeah its a powermaster. Do you know where I can get a replacement and how much they are.
