Brake Booster Testing

[John Slade <edalsj@igs.net>]

Does anyone know of a reasonable out-of car method for testing brake
booster units? I there a home bench method? Is this something that a
well set up commercial auto maintenance place...garage, dealer etc...can
do without a great deal of fuss?

Anyone gone this route, rather than installing it (them) in your car,
only to find that they are not working.
