I am trying to determine if I really did kill my booster or not and Id like someone that really knows and understands these systems to chime in if possible.
1967 Newport...possibly Bendix? single diaphragm power drum.
I still have brake assist.
I do not have a constant hissing inside the car.
I do have a momentary hiss inside the car when I depress the pedal...only for the first 1/2" or so of travel, then it goes away.
I can force the hiss to stay constant if I keep the pedal within that initial region of travel.
I'm not sure what else to point out.
I'm wondering if I have a seal that is failing, or the control valve is failing? or if its actually working as it should and the noise I'm hearing is just the initial pressure difference when the valve opens and I'm just needing an adjustment somewhere. I do not believe it to be the original booster, but a replacement.
