My daily driver is 22 years old. The brakes work just fine, are up to date with maintenance, but when I drive customers' cars I am amazed at how smartly the cars stop, compared to mine. I know the booster (vacuum assist) works, but I can't possibly remember how they performed when new.
So is it an either / or situation? I mean do they die, or does the boost effectiveness gradually fade?
