Brake booster removal question

cudamark said

The rebuilder won't need the brackets to work on the booster. It's just a matter of what finish you want on the brackets. IIRC, they originally had a cadmium type plating on them. If the booster is going to get that finish, it might be cheaper and more convenient to have the rebuilder do the brackets too, if you're looking to restore those parts back to original.

Thanks a lot.
I don't want to have the bracket restored. It's in a good original shape.
I would like to have my booster rebuilt, not for the show, but because since a couple of days, I have no brake anymore on my Demon.
It happened suddenly. Before that, the braking was very correct. Now, the brake pedal is excessively hard and inefficient.
As the breakdown happened very suddenly, I think it's the booster that gave up
