But if it's dying or is giving signs of passing on then rebuilding it or going the Autozone route IMO is a crap shoot and will probably lead to you just swapping it out for Vac or Hydro later on.

If $$ not a concern I do agree that the line pressure of the Hydro is very appealing especially if you don't want to deal with a transbrake and like big brake kits that excel under better line pressures.

I went vacuum, mainly because it was new for like $1XX some bucks and I have one freebie stop if the car stalls etc at regular pedal feel. I had one instance on my Powermaster that gave me a brick pedal for a few seconds and knew that if it ever died I'd probably be DOA, I believe Hydroboost has the same weak point on an engine stall etc.

While it is true.... you only have an accumulator to "store" pressure for a brake hit or two while the engine isn't running........ it is my understanding.... that even after all the pressure is relieved from the accumulator.... like if the motor was dead..... you still have the equivalent of manual brakes......

On the PM... I think you just have a rock hard pedal.... and maybe 10% if any braking effect when you push the brakes until your face looks like ....
