Can a brake booster be tested without starting the vehicle?
I have a hand vaccum pump tester thing and i attached it to the booster and pumped it up to 20 and stopped, the booster held the vaccum for 30 min without leaking before i unhooked it.
Is there anything else that can go wrong with a booster except for leaking to make it bad?

Thanks
