testing Bendix Boosters

[hemi68charger]

Hey Gang..
I have a sneaky suspicion that the booster on Daytona's got a leak. I just installed the Cheetah valve body in my Daytona and tested it while on jack stands. Going through the gears like usual, I apply the brakes. The booster (I'm assuming it is that), made a quick and gone whistle. It didn't remain with the brakes applied. Maybe it is a vacuum leak? I guess I could run the engine with the hose disconnected and the nipple plugged and see if it does it. If it doesn't, is there a way to isolate the booster to determine if it is bad? Also, I have a couple of spare Bendix booster in the attic. Can I "bench" test them too utilizing the vacuum source of the engine while it is running? Maybe get a long hose and connect it and fire up the motor and see if I "hear" anything?

Also, if it is bad, is there a company out there that has a good rebuilding service with a decent turnaround time?

Thanks..
T

Cool, but is there a way to test a booster before you ship it off? I want to verify mine isn't malfunctioning and see if one of the others I have had for a long time are good....

If you have a vacuum hand pump, I would try to adapt that to it and see if it will hold a vacuum.  If not, then I would imagine that it is bad.

Prior Brake in TX rebuilt mine.  Cost around $100.  They used to be the rebuilders for all of NAPA stuff.
