Yeah I have a check valve but someone said there is some kind of filter between the manifold and the check valve. I've never seen or heard of one but he said the newer cars have them.

New stuff could have an inline filter...The filter on the older stuff is usually at the brake pushrod, under the dash..That's where the atmospheric pressure enters the booster when you step on the brakes.

(remember, vacuum does no work, the atmospheric pressure does the pushing...)

Let off the brakes and the air on the backside of the diaphram gets sucked into the intake manifold, hence the need for a filter.

Later, mikey

Hmm.. this is an interesting question.. The truck I am building up at the moment has a vacuum reservoir.. a tank, about 5 gallons I'd guess.. It's connected to the intake manifold from the top of the tank and incorporates a check valve.. The tank has been sitting for about 8 years..

I havent started the new engine yet (383cu chev), if the inside of the reservoir tank was rusty, or dusty.. wouldnt these contaminants potentially make it into the engine? What sort of filter would one add if it was deemed prudent?

Cheers, Duncan.

I have never put an inline air filter on or seen one sold by an aftermarket vendor. I always thought that if all they wanted was the one at the pushrod, why complicate things.

If you really want to add an inline filter in, maybe find the application that your friend spoke of and go to the dealer.

Or you could use an inline fuel filter.
That would probably work for Duncan M and his 5 gallon tank as well. I'd use a large canister type for that one.

Later, mikey

RE:A filter on your brake booster

Hi in the mid 70's some of the chev 4x4's came with a inline filter, between the manifold and booster, it looks like a gas filter but half the size and black not clear, my K5 still has it on it. TROY

I thank you all for this info. I should have said it's a 51chevy 3/4 ton with a 350 HO crate and 700R4 so can't go to the dealer.
I'll check with NAPA.

My 77 truck has one. I think it's a charcoal filter to keep gas fumes from rotting the booster diaphram.
