What is it and were does it go? (Page 2/2)

Is deleting the filter the preferred method or new filter?



Once I got my Indy's engine running, it became apparent the power brake vacuum booster was no good so I replaced it.
Sometime later when driving, my brake "disappeared" because of lack of vacuum.
The filter had clogged with "rubber dust" in the line from the original brake booster's disintegrating diaphram.

Obviously the filter did its intended job by keeping that crap out of the engine.
I took it out and blasted the line clear with compressed air before installing a new one.

Just saying it does have a purpose or GM wouldn't have put one in.

And yet, they stopped using it.

I personally view that filter as a safety hazard. If it clogs up, you have no power brakes. And that can get you killed. Without that filter, the engine may ingest some debris. And it may damage the engine. But that's nowhere near as dangerous as brake failure.

They found out they could save 10 cents per car... ?

Pretty sure in my case, the Indy had sat for 20 years and the booster diaphram dried up into dust.
My mistake was I didn't blow out the line when I replaced the booster.

Guys... anytime you replace the booster, blow out the line with compressed air.
