Replacing Brake System

I am replacing my brake components calipers, lines, proportioning valve and master cylinder. If everything is new is it necessary to bench bleed the master cylinder? I will be using a vacuum bleeder to bleed the system. Thanks in advance for any advice.

You have to bench bleed before you hook up the lines. This can be on the bench with a vice and screwdriver or in the car with short lines that go back into the master resevoir.

I must be missing something If it s A complete new system the fluid will just flow out make you re-fill several times What would be the advantage of getting the fluid in when your just gonna suck it right through?

Thanks for everyones input. I was thinking like Vader Vette That you would be sucking thru the entire system anyway. Guess I will be bench bleeding.

Now does this mean that if the cylinder goes dry during the bleeding process you should bench bleed it again, not trying to be a smart a** just want to do it right.
