Bendix Brakes won't air up

[mbulriss]

Al,

The 6 ton jack stands are a good thing to have. Do you also have the
20 ton hydraulic jack that used to come with the Birds?

In any event, be careful. I am assuming the Bendix air dryer was
serviced at the time the brakes were worked on. Not sure which Bendix
you have, but look for any obvious loose fittings on the Bendix dryer.
If you start the engine and crawl under, it should be obvious where
the air hiss is coming from. I had the AD-2 dryer and spitter valve
serviced on my 83 PT40 and on the very next trip lost all air pressure
after about 50 miles of travel. The over-pressure pop-off valve on
the side of the dryer had aparently gotten cleaning fluid on the
threads which apparently allowed it to vibrate loose and fall off.
It had not been touched during the dryer service. Hopefully you just
have vibrated a fitting loose on the air dryer.

Good luck,
