Brake booster

[crawler 129]

bought a 84 k10 and the booster was leaking around the pedal . So I changed it and still leaks . Been thru 3 boosters and all leak .

Am I missing something or just getting ng parts . 2 from napa and 1 from advance.

I tried auto zone here but they don't know what a booster is or how to look it up .

All 3 parts stores around here use the same part number , I assume getting parts from the same warehouse .

I asked a buddy that runs a shop and he said parts quality is down bad they are having tough times with changing parts .

Any help or advise would be great !

Thanks . Tried oreilys yesterday and it was ng as well . Up to 4 now .

Positive thing is labor time says 1.5 . I can do it less than 20 .

all the parts stores around here get reman the same part number from the same warehouse . They can't get a new one .

Called lmc for a new one but they are back ordered .

In past I've had issues with rock auto and they won't return a email so don't care for them.

Looking at trying one from national parts depot Chevy catalog now .

Understandable there. They may list a different part number for you to find from a different vendor.

Have they all had vacumn leaks at the push rod? If you lived closer I'd give you a used one to try

 

[crawler 129]

Yes sir all at the push rod inside the cab.

 

[baldduck74]

Asking because I've had them hiss before, at the push rod, done vacuum checks with propane, carb cleaner, brake clean. With no vacuum leaks.

 

[crawler 129]

When I press the brake pedal down it hisses and the engine idle changes .

 

[baldduck74]

It will do that, is engine high mileage?
Or built with a rowdy cam

 

[crawler 129]

Stock engine unknown mileage .

I've owned 15 of these trucks and never had to change a booster and have never heard one leak before .

I have checked the boosters with a mighty vac and they do not hold pressure . They leak down.

Ended up getting one off an old cab and it works .
