Default Need some advice on power break booster pump noise
Should get my Cobra in time for Thanksgiving and have been reviewing the videos I took prior to the 78 mile debacle, one thing I noticed was when I turned on the ignition key the power break booster pump made a loud humming noise, like it was priming itself, I was told this is normal by the installer. Also, when I hit the break pedal, same thing, a loud humming noise, so is this what I can generally expect or should it be silent?? I have never driven a car with a power break booster pump that I was aware of so I don't have such knowledge on the correct noise level, if any.

Can anyone share their experiences with such an application?

Thanks, John, AKA, tin-man
